    KANNE, Circuit Judge. Spencer Harris was convicted

    count of distributing crack cocaine, 
    21 U.S.C. §§ 841
    (a)(1),
    (b)(1)(B), one count of distributing powder cocaine,
    
    id.
     §§ 841(a)(1), (b)(1)(C), one count of possessing crack
    cocaine with intent to distribute, id. §§ 841(a)(1), (b)(1)(B),
    one count of being a felon in possession of a firearm,
    
    18 U.S.C. §§ 922
    (g)(1), 924(c)(1)(B), and one count of
    possessing a firearm in furtherance of a drug-trafficking
    crime, 
    id.
     § 924(c)(1)(A). The district court sentenced
    Harris to a total of 460 months’ imprisonment. On appeal,

    Harris claims that the district court made several
    erroneous evidentiary rulings, which deprived him of a
    fair trial. We do not believe that the district court
    abused its discretion in admitting the challenged evidence
    against Harris, so we affirm his conviction.
    Because Harris’s crimes involved crack cocaine, after
    oral argument we ordered the parties to file supple-
    mental memoranda on the propriety of the district court’s
    sentence in light of Kimbrough v. United States, 
    128 S. Ct. 558
    (2007), and United States v. Taylor, 
    520 F.3d 746
     (7th Cir.
    2008). After considering the parties’ responses, we do not
    believe that Kimbrough or Taylor invalidates Harris’s
    sentence, so we affirm the sentence as well.
    I. HISTORY
    On June 22, 2006, officers of the Springfield, Illinois,
    Police Department arrested David Haynes for possession
    of crack cocaine and marijuana that the officers recovered
    from a baby seat in Haynes’s house during a parole
    check. After his arrest, Haynes agreed to cooperate with
    the police and to provide information about Spencer
    Harris, whom Haynes claimed sold him the crack cocaine.
    Haynes explained to the police that he could set up a
    drug purchase from Harris at any time, merely by tele-
    phoning him.
    The Springfield police officers brought Haynes to meet
    with Drug Enforcement Administration (DEA) agents,
    who arranged for Haynes to participate in two con-
    trolled purchases of drugs from Harris. At the agents’
    direction, Haynes attempted to contact Harris on Harris’s
    cell phone to schedule a meeting to purchase drugs. The
    No. 07-2195                                              3
    agents outfitted Haynes with audio and video re-
    cording equipment, searched him to ensure that he was
    not carrying contraband, and gave him money to pur-
    chase cocaine—preferably crack cocaine—from Harris.
    The first controlled purchase occurred on the day of
    Haynes’s arrest. Haynes first tried contacting Harris
    using a DEA office telephone, to no avail. Haynes then
    placed a second call to Harris from his personal cell
    phone, and Harris’s girlfriend answered. Haynes arranged
    to meet Harris at the residence of Harris’s girlfriend,
    located at 1904 Greentree Street, in Springfield, Illinois.
    There, Harris sold powder cocaine to Haynes and agreed
    to convert the powder into crack cocaine while Haynes
    waited; however, Harris could not find baking soda,
    so Haynes left with the powder cocaine. Haynes then met
    the DEA agents, who searched Haynes, recovered the
    powder cocaine from him, and downloaded the audio
    and video recordings onto a computer.
    The second controlled purchase took place one week
    later at Harris’s home, located at 1844 South 14th Street,
    also in Springfield, Illinois. Haynes again arranged the
    meeting with Harris by cell phone, and DEA agents
    met Haynes at a nearby golf course, where they sup-
    plied him with recording equipment and a bicycle,
    searched him for contraband, and provided him with
    money. Haynes cycled to Harris’s house and met Harris
    in the backyard. Haynes purchased crack cocaine from
    Harris, and then immediately returned to the golf course,
    where the DEA agents recovered the crack cocaine and
    downloaded the new audio and video recordings.
    Law enforcement officers conducted surveillance of
    both controlled purchases, and then obtained search
    warrants for both residences. The officers executed the
    4                                               No. 07-2195
    warrants on July 6, 2006. At Harris’s girlfriend’s resid-
    ence, the officers found a .22 revolver locked in a dresser
    drawer, 9mm ammunition, powder cocaine, and crack
    cocaine. At Harris’s residence, the officers discovered
    a loaded 9mm semi-automatic pistol in a bag on the
    kitchen table, powder cocaine, crack cocaine, digital
    scales, individual plastic bags, drug-cutting parapher-
    nalia, and $2,000 in cash. The officers arrested Harris. At
    the time of his arrest, Harris had a key to his own house,
    a key to his girlfriend’s house, and a key to the locked
    dresser drawer from which the .22 revolver was recovered.
    A federal grand jury issued an indictment that charged
    Harris with five counts: (1) knowingly and intentionally
    distributing five or more grams of a mixture or sub-
    stance containing cocaine base, 
    id.
     §§ 841(a)(1), (b)(1)(B);
    (2) knowingly and intentionally possessing with intent to
    distribute, five or more grams of a substance containing
    cocaine base, 
    21 U.S.C. §§ 841
    (a)(1), (b)(1)(B); (3) being a
    felon in possession of a firearm, 
    18 U.S.C. §§ 922
    (g)(1),
    924(c)(1)(B); (4) possessing a firearm in furtherance of a
    drug trafficking crime, 
    id.
     § 924(c)(1)(A)(I); and (5) know-
    ingly and intentionally distributing a mixture or sub-
    stance containing cocaine, 
    21 U.S.C. §§ 841
    (a)(1), (b)(1)(C).
    Count 1 of the indictment was based on the crack cocaine
    sold to Haynes at the second controlled purchase. Counts
    2, 3, and 4 were based on the crack cocaine and the 9mm
    pistol seized from the officers’ execution of the search
    warrants. And Count 5 was based on the powder cocaine
    sold to Haynes at the first controlled purchase.
    In anticipation of trial, the government gave notice of
    its intent to present evidence of other crimes, wrongs, or
    acts committed by Harris. See Fed. R. Evid. 404(b). The
    government’s notice delineated the “other act” evidence
    No. 07-2195                                               5
    that it intended to offer: (1) Harris sold cocaine and crack
    cocaine to Haynes on numerous occasions prior to the
    controlled purchases; (2) during the same period, Harris
    transacted a number of drug deals with two other individ-
    uals, Troy Powers and Mario Brown; (3) Harris drove
    a number of luxury vehicles, including a black Lexus;
    and (4) in addition to the charged firearm, officers recov-
    ered the .22 revolver and 9mm ammunition during
    their searches. In response to the government’s notice,
    Harris filed a motion in limine, which sought to bar the
    evidence of prior drug deals with Haynes, Powers, and
    Brown as irrelevant and as improper propensity evi-
    dence under Rule 404(b). Harris’s motion also sought
    to keep out the evidence of the luxury vehicles and the
    recovered-but-uncharged revolver and ammunition as
    irrelevant and unfairly prejudicial.
    The district court held a hearing on Harris’s motion in
    early October 2006. With regard to the prior drug deals
    between Harris and Haynes, the district court stated that
    “those transactions . . . are relevant to show the history
    between the two. And in that sense they are intricately
    related to the charges found in . . . the indictment. So
    things that go to their history and relationship are very
    relevant and will not be barred.” The district court ex-
    plained that the evidence was also admissible under
    Rule 404(b) because it “would go to show the defendant’s
    knowledge of cocaine, his intent to distribute it, and
    it would go towards establishing the nature and extent
    of the relationship between the defendant and [Haynes].”
    As for the drug transactions between Harris and Powers
    and between Harris and Brown, the district court ex-
    plained that:
    [E]vidence of those should be limited to the same
    time frame that [Haynes] was purchasing crack or
    6                                              No. 07-2195
    powder cocaine from [Harris]. For that time frame
    the other incidents are relevant as corroboration of
    [Haynes’s] testimony, and to show that there
    was a source that Harris had for purchasing the
    cocaine that he in turn sold as cocaine or crack
    cocaine.
    The district court also determined that the evidence that
    Harris drove luxury vehicles would “be relevant to
    show an unaccounted for source of income if the Gov-
    ernment is able to introduce other evidence that the
    defendant lacked a source of income.” The district court
    explained that the probative value of the vehicle evidence
    would not be outweighed by prejudice, “because there’s
    nothing inherently illegal or improper about owning
    or driving a Lexus automobile.” Finally, with respect to
    the .22 revolver and the ammunition, the court stated
    “[t]he second gun doesn’t add much prejudice to the first
    gun, which is required under the Government’s indict-
    ment, if it’s going to prove its charge.”
    The day after the hearing, Harris pled not guilty to all
    five counts in the indictment, and the case proceeded to
    a jury trial. During the government’s case-in-chief, the
    government introduced testimony from Haynes, Powers,
    Brown, Harris’s girlfriend, and several DEA agents, as
    well as physical evidence and the audio and video record-
    ings from the controlled purchases. The recordings por-
    trayed Harris meeting with Haynes, the two men con-
    versing about basketball shoes, and Harris counting
    money. The recordings did not show drugs being trans-
    ferred, nor did they contain dialogue about the drug
    transactions.
    In order to place its evidence of the controlled pur-
    chases into context, the government elicited testimony
    No. 07-2195                                               7
    about other drug deals between Haynes and Harris. But
    before Haynes could testify to his prior dealings with
    Harris, the district court gave a limiting instruction to
    the jury:
    Ladies and gentlemen, you’re now hearing testi-
    mony about drug transactions other than those
    charged in the indictment. The ones charged in the
    indictment were in June of 2006. I want you to
    understand that this evidence of other drug trans-
    actions is admitted for the limited purpose of
    showing the defendant’s knowledge of the drugs
    involved, his intent with respect to them, and the
    relationship and history between the defendant
    and this witness. You’re to consider the evidence of
    these uncharged drug transactions only in those
    respects, and for those limited purposes.
    After the district court’s limiting instruction, and over
    the objection of Harris’s counsel, Haynes explained that
    he was a drug dealer and that he was introduced to
    Harris in 2004 because he needed a new supplier of crack
    cocaine. Haynes stated that he purchased a quarter ounce
    of crack cocaine from Harris for $250 the first time they
    met, and Haynes recounted how he regularly purchased
    crack cocaine from Harris for $250 per quarter ounce
    whenever Haynes wanted after placing a quick call to
    Harris’s cell phone. Haynes specified that he engaged
    in drug transactions with Harris about three or four
    times per week until Haynes went to prison in March 2005;
    once Haynes was released from prison in September 2005,
    he purchased about a quarter ounce of crack cocaine from
    Harris two or three times per day until his arrest. Haynes
    added that he also purchased a quarter ounce of crack
    cocaine from Harris for $250, without the knowledge of
    8                                              No. 07-2195
    the DEA, after the controlled purchases; the district
    court repeated its limiting instruction before Haynes
    testified about the subsequent drug deal.
    Haynes testified that he had purchased drugs from
    Harris on other occasions at both residences where the
    controlled purchases occurred, and Haynes stated that
    Harris had converted powder cocaine to crack for him
    on other occasions. Haynes also testified that, on one
    occasion, he had seen the butt of a 9mm pistol sticking
    out of a couch in Harris’s house. Haynes told the jury
    that when he asked Harris about the gun, Harris told
    him that he needed it for protection. Harris told Haynes
    that he was concerned because Brown had been arrested
    while driving away from Harris’s house after a drug deal,
    and Harris was worried that Brown’s family might come
    after him.
    The government later called Powers and Brown as
    witnesses to testify about other drug deals involving
    Harris. Powers testified that he sold cocaine to Harris
    three or four times, beginning in 2005. Powers told the
    jury that when he and Harris met, they negotiated a
    purchase price by silently entering dollar amounts into a
    cell phone and passing the phone between them—the two
    rarely spoke and acceded to terms by nodding their
    heads. Brown testified that he purchased powder co-
    caine from Harris at Harris’s residence on six occasions
    between the fall of 2004 and May 2005.
    The government also introduced the other evidence it
    specified in its pre-trial notice of intent. Evidence that
    Harris drove luxury vehicles came in through several
    witnesses. Harris’s girlfriend testified that Harris was not
    employed from 2003 until his arrest in 2006. Despite
    Harris’s unemployment, Haynes saw him driving a Nissan
    No. 07-2195                                             9
    Pathfinder and a black Lexus, and Harris’s girlfriend
    confirmed that Harris drove these vehicles, in addition
    to an Infinity sport-utility vehicle and a tan-colored
    vehicle. Harris’s girlfriend testified that the Pathfinder
    was titled in her mother’s name, two of the vehicles
    were titled in Harris’s aunt’s name, and the tan-colored
    vehicle was titled in Harris’s six-year-old son’s name.
    The government introduced testimony about the second
    gun and ammunition through DEA witnesses, who testi-
    fied that a .22 revolver and 9mm ammunition had been
    recovered from Harris’s girlfriend’s residence. A DEA
    expert witness explained that drug dealers often arm
    themselves to protect their person, drugs, and cash.
    In his defense, Harris argued that Haynes had set him
    up in order to secure lenient treatment from the gov-
    ernment in his own case. Harris bolstered this argument
    by highlighting that the recordings presented at trial did
    not show any drugs changing hands. Harris also argued
    that the evidence collected during the two searches did
    not belong to him. For example, Harris’s counsel argued
    in closing that “[t]he .22 is found in [Harris’s girl-
    friend’s] house. It is in [her bedroom]. It is in [her]
    dresser . . . . It is [her] gun and she had it for her own
    protection.” Harris’s counsel suggested that the drugs
    found at Harris’s girlfriend’s house were part of her
    own “personal stash.” Harris argued, in the alternative,
    that even if some of the drugs recovered during the
    police searches belonged to him, they were merely for
    his personal use and were not intended for distribution.
    At Harris’s request, the district court revised and ex-
    panded its limiting instruction prior to the jury’s delib-
    erations. The new instruction explained that the “evidence
    of other acts” was “not evidence that [Harris] committed
    10                                             No. 07-2195
    the acts alleged in the indictment at the times alleged.”
    The court instructed the jury that such evidence should
    be considered “only on the question of motive, identity,
    or plan, or whether any acts of the defendant alleged in
    the indictment, if proven, were done with knowledge,
    intent, absence of mistake, or were not inadvertent acts.”
    The instruction also reiterated that the government had
    the burden of proving the acts alleged in the indictment
    beyond a reasonable doubt. The jury deliberated and
    found Harris guilty on all five counts of the indictment.
    A probation officer then prepared a presentence investi-
    gation report (PSR), in which the officer determined that
    Harris was a career offender, see U.S.S.G. § 4B1.1(a),
    because he had two prior qualifying felony convictions—an
    Illinois conviction for aggravated battery, and an Illinois
    conviction for manufacture or delivery of a controlled
    substance. The probation officer accordingly assigned
    Harris an offense level of 37 and a Criminal History
    Category of VI. See id. §§ 4B1.1(b), (c)(2); see also 
    21 U.S.C. § 841
    (b)(1)(B) (setting statutory maximum for
    distribution of controlled substance at life if defendant
    has prior final felony drug conviction). Based on these
    calculations, the PSR listed Harris’s guideline imprison-
    ment range as 420 months to life, see U.S.S.G.
    § 4B1.1(c)(2)(A), and the probation officer recommended
    a prison term of 420 months. Neither Harris nor the
    government objected to the PSR.
    At the sentencing hearing, the government recommended
    that Harris receive a life sentence. Harris’s counsel asked
    for a sentence between 300 and 360 months, arguing that
    a higher sentence would result in a de facto life sentence
    for Harris. The district court adopted the PSR without
    change, considered the arguments advanced by the
    parties, and canvassed several of the sentencing factors
    No. 07-2195                                                  11
    enumerated in 
    18 U.S.C. § 3553
    (a). The court then sen-
    tenced Harris to 400 months’ imprisonment on the distrib-
    ution and possession-with-intent-to-distribute counts
    (Counts 1, 2, and 5), and to 120 month’s imprisonment
    on the felon-in-possession count (Count 3), to run con-
    currently; the court also sentenced Harris to 60 months’
    imprisonment on the possession-of-a-firearm-in-relation-
    to-drug-trafficking count (Count 4), to run consecutively.
    This yielded a total sentence of 460 months’ imprisonment,
    to which the court added eight years of supervised re-
    lease and a $500 special assessment.
    II. ANALYSIS
    Harris claims on appeal that he is entitled to a new
    trial because of the district court’s evidentiary rulings.
    Harris argues that “[w]hether viewed individually or in
    their totality,” these rulings denied him a fair trial. Specifi-
    cally, Harris contests the admission of: (1) testimony
    about drug transactions with Haynes other than the
    controlled purchases; (2) testimony about the prior drug
    transactions with Powers and Brown; (3) testimony about
    the luxury vehicles; and (4) evidence of the uncharged .22
    revolver and 9mm ammunition. Harris contends that
    the government’s closing argument demonstrates why
    the evidence was erroneously admitted. In his supple-
    mental memorandum, Harris asks that his sentence be
    reversed in light of Kimbrough v. United States, 
    128 S. Ct. 558
    (2007).
    A. The district court’s evidentiary rulings
    We review the district court’s evidentiary rulings for
    an abuse of discretion, United States v. Owens, 
    424 F.3d 649
    ,
    12                                               No. 07-2195
    653 (7th Cir. 2005), including its decision to admit evidence
    of “other acts” under Federal Rule of Evidence 404(b),
    United States v. Price, 
    516 F.3d 597
    , 603 (7th Cir. 2008), and
    its decision to admit evidence under the “intricately
    related” doctrine, United States v. Wantuch, 
    525 F.3d 505
    ,
    517 (7th Cir. 2008).
    1. Testimony about other drug deals with Haynes
    The district court justified its admission of testimony
    about other drug transactions between Harris and Haynes
    because such testimony was “intricately related” to the
    conduct charged in the indictment, see 
    id. at 517
    ; United
    States v. Strong, 
    485 F.3d 985
    , 989-90 (7th Cir. 2007), and
    because the evidence was admissible under Federal Rule
    of Evidence 404(b). Harris contends that the district
    court improperly admitted the testimony because it was
    not intricately related to the charged conduct and because
    it was improper propensity evidence. See Fed. R. Evid.
    404(b); United States v. Simpson, 
    479 F.3d 492
    , 496-97 (7th
    Cir. 2007).
    Rule 404(b) prevents the admission of evidence of other
    crimes, wrongs, or acts to prove that a person acted in
    conformity with his prior conduct. Fed. R. Evid. 404(b). In
    other words, “Rule 404(b) plainly prohibits the govern-
    ment from introducing evidence of prior bad acts to
    show that the defendant’s character is consistent with a
    propensity to commit the charged crime.” Simpson, 
    479 F.3d at 497
    . But evidence may be properly admitted under
    Rule 404(b) for a non-propensity purpose, such as to
    prove “ ‘motive, opportunity, intent, preparation, plan,
    knowledge, identity, or absence of mistake or accident.’ ”
    United States v. Sebolt, 
    460 F.3d 910
    , 916 (7th Cir. 2006)
    No. 07-2195                                                 13
    (quoting Fed. R. Evid. 404(b)). A district court properly
    admits evidence of prior acts under Rule 404(b) if:
    “(1) the evidence is directed toward establishing a
    matter in issue other than the defendant’s propen-
    sity to commit the crime charged; (2) the evidence
    shows that the other act is similar enough and close
    enough in time to be relevant to the matter in issue;
    (3) the evidence is sufficient to support a jury
    finding that the defendant committed the similar
    act; and (4) the probative value of the evidence is
    not substantially outweighed by the danger of
    unfair prejudice.”
    United States v. Moore, No. 07-3445, slip op. at 6 (7th Cir.
    July 1, 2008) (quoting United States v. Ross, 
    510 F.3d 702
    ,
    713 (7th Cir. 2007)); United States v. Dennis, 
    497 F.3d 765
    ,
    768 (7th Cir. 2007) (quoting Sebolt, 
    460 F.3d at 916
    ).
    Acts that are “intricately related to” (or “inextricably
    intertwined with”) a crime charged in the indictment “are
    generally admissible . . . and are not subject to the con-
    straints of [Rule 404(b)].” Strong, 
    485 F.3d at 989-90
    ; see
    also United States v. James, 
    464 F.3d 699
    , 709 (7th Cir.
    2006); United States v. Senffner, 
    280 F.3d 755
    , 764 (7th Cir.
    2002). But we recently noted that the “ ‘inextricably inter-
    twined’ formula . . . is unhelpfully vague.” United States
    v. Taylor, 
    522 F.3d 731
    , 734 (7th Cir. 2008). We explained
    that “intent and absence of mistake are express ex-
    ceptions to the Rule 404(b) bar; there is no need to
    spread the fog of ‘inextricably intertwined’ over them.
    Almost all evidence admissible under the ‘inextricably
    interwoven’ doctrine is admissible under one of the
    specific exceptions in Rule 404(b) . . . .” 
    Id. at 735
    . After
    reviewing the record, we believe that there is “no need
    to spread the fog” of the “intricately related” doctrine
    in this case because Haynes’s testimony about his other
    14                                              No. 07-2195
    drug transactions with Harris was admissible under
    Rule 404(b).
    Haynes’s testimony related to several non-propensity
    issues, including Harris’s intent to distribute the drugs
    recovered during the police searches, his knowledge of
    the drugs, and the absence of mistake. Evidence that
    Harris sold drugs to Haynes was relevant to show that
    Harris intended to sell the drugs found during the
    police searches, and Harris’s intent was automatically
    at issue because the indictment charged him with specific
    intent crimes. See Ross, 
    510 F.3d at 713
     (“Because con-
    spiracy is a specific intent crime, whether Wilson in-
    tended to conspire to rob the post office was automatically
    in issue.”); United States v. Puckett, 
    405 F.3d 589
    , 596 (7th
    Cir. 2005) (“The crime of possession of cocaine with
    intent to distribute, in violation of 
    21 U.S.C. § 841
    (a)(1),
    is a specific intent crime making the defendant’s state
    of mind an element of the crime which is to be determined
    by the finder of fact.”); see also Moore, No. 07-3445, slip
    op. at 6-7. In fact, Harris also placed his intent squarely
    at issue by claiming that he possessed the drugs merely
    for personal use. The evidence of other transactions
    directly rebutted Harris’s asserted defense to the
    possession-with-intent-to-distribute charge by showing
    that Harris had engaged in drug deals in the past. See
    Moore, No. 07-3445, slip op. at 7-8; Taylor, 
    522 F.3d at 734
    ;
    United States v. Jones, 
    455 F.3d 800
    , 808 (7th Cir. 2006);
    Puckett, 
    405 F.3d at 596
    . The testimony from Haynes
    also disproved Harris’s contention that the drugs and
    the firearms seized during the searches of 1904 Green-
    tree Street and 1844 South 14th Street belonged to his
    girlfriend and other tenants: the fact that Harris had
    engaged in other drug transactions proved that Harris
    No. 07-2195                                              15
    had knowledge of the drugs and firearms recovered. See
    United States v. Best, 
    250 F.3d 1084
    , 1092 (7th Cir. 2001).
    The testimony from Haynes was also relevant to rebut
    the allegations of mistake that Harris raised by claiming
    that he was an innocent bystander and that Haynes
    “set him up.” See Moore, No. 07-3445, slip op. at 7-8.
    Harris’s counsel argued multiple times that Haynes
    provided evidence against Harris in an attempt to
    procure lenient treatment after officers discovered crack
    cocaine in a baby seat at Haynes’s house. And Harris’s
    counsel repeatedly noted that the audio and video re-
    cordings presented at trial lacked discussion about
    drugs—the recordings revealed a conversation between
    Harris and Haynes about basketball shoes, and showed
    Harris counting cash. By combining these points,
    Harris’s counsel accused Haynes of fabricating evi-
    dence against Harris.
    The government therefore needed to introduce evi-
    dence of the illicit history between Harris and Haynes
    in order to elucidate their ongoing business relationship
    and rebut Harris’s attempt to downplay his role in the
    controlled purchases. See Moore, No. 07-3445, slip op. at 7-
    8; Taylor, 
    522 F.3d at 733
     (“The buyers’ previous knowl-
    edge about [the defendant] related to the accuracy
    (hence absence of mistake) of their testimony concerning
    the controlled buys that provided crucial evidence for
    the government’s case.”). The evidence of identical prior
    transactions related to the accuracy of the testimony
    concerning the controlled purchases by explaining how
    Haynes’s relationship with Harris developed to the
    point that Haynes could easily purchase drugs from
    Harris after only a quick phone call. The prior transac-
    tions also helped explain why Harris did not answer the
    16                                            No. 07-2195
    initial telephone call placed from the DEA office phone
    (presumably a number unknown to Harris), but accepted
    the call placed from Haynes’s personal cell phone. Simi-
    larly, the evidence of prior drug transactions at Harris’s
    girlfriend’s house tied Harris “to the house (where those
    items were found) and helped explain why he would
    possess the items.” Cf. Strong, 
    485 F.3d at 990
     (upholding
    admission of evidence under the “intricately related”
    doctrine).
    The testimony from Haynes also satisfies the other
    prongs of our test for review under Rule 404(b). The
    testimony was “similar enough and close enough in time”
    to the charged conduct—in fact, the transactions were
    limited to a two-year period and involved identical
    amounts of the same drug as those charged in the indict-
    ment. See Ross, 
    510 F.3d at 713
    ; United States v. Ruiz, 
    178 F.3d 877
    , 880-81 (7th Cir. 1999); United States v. Gibson,
    
    170 F.3d 673
    , 679 (7th Cir. 1999). The evidence was also
    sufficient to support a jury finding that Harris engaged
    in the prior drug transactions with Haynes: the evidence
    of the controlled purchases and the items recovered from
    the residences, as well as Powers’s and Brown’s testimo-
    nies, corroborated Haynes’s coherent story. See United
    States v. Mallett, 
    496 F.3d 798
    , 802 (7th Cir. 2007).
    And the evidence satisfies the final prong of our
    Rule 404(b) admissibility inquiry—the balancing test
    incorporated from Federal Rule of Evidence 403. See
    Moore, No. 07-3445, slip op. at 6 (quoting Ross, 
    510 F.3d at 713
    ). Rule 403 provides that relevant evidence “may
    be excluded if its probative value is substantially out-
    weighed by the danger of unfair prejudice, confusion of
    the issues, or misleading the jury, or by considerations
    of undue delay, waste of time, or needless presentation of
    No. 07-2195                                              17
    cumulative evidence.” Fed. R. Evid. 403. “[A]dmission of
    evidence under Rule 403 is entitled to special deference.
    ‘Only in an extreme case are appellate judges competent
    to second-guess the judgment of the person on the spot,
    the trial judge.’ ” Wantuch, 
    525 F.3d at 518
     (quoting
    Strong, 
    485 F.3d at 991
    ); see also United States v. Gardner,
    
    211 F.3d 1049
    , 1055 (7th Cir. 2000). “Evidence is unfairly
    prejudicial only if it will induce the jury to decide the
    case on an improper basis, commonly an emotional
    one, rather than on the evidence presented.” Wantuch,
    
    525 F.3d at 518
    .
    We have already explained that the testimony about
    other drug transactions between Harris and Haynes had
    a great amount of probative value on the issues of
    intent, absence of mistake, and knowledge, especially
    in light of Harris’s asserted defenses. See Moore, No.
    07-3445, slip op. at 8. Contrary to Harris’s suggestion,
    the district court did not allow the government to directly
    elicit testimony that Harris and Haynes had engaged
    in hundreds of drug transactions—Haynes testified to a
    pattern of prior drug transactions that occurred at reg-
    ular intervals involving the same amounts of the same
    drug charged in the indictment. We do not believe that
    the protocol that Haynes described was inherently “emo-
    tional or incendiary.” See Strong, 
    485 F.3d at 991
    . Still,
    the number of other drug transactions was not probative
    to explain the charged crime, and the government con-
    ceded at oral argument that testimony regarding the
    prior drug deals between Harris and Haynes could have
    been elicited in a way that prevented Haynes from
    stating that he purchased crack cocaine several times per
    week and then several times per day over lengthy periods
    of time. Standing alone, evidence regarding a vast num-
    18                                             No. 07-2195
    ber of similar drug deals might allow a jury to improp-
    erly convict a defendant based on his propensity to sell
    drugs. See Simpson, 
    479 F.3d at 499
    . But in this case,
    Haynes’s testimony did not stand alone. The district
    court gave numerous and detailed limiting instructions
    on the issue. These instructions alleviated any potential
    prejudice caused by the testimony. See United States
    v. Hearn, No. 07-1613, slip op. at 14 (7th Cir. July 18,
    2008); Moore, No. 07-3445, slip op. at 9; Wantuch, 
    525 F.3d at 518
    ; Mallett, 
    496 F.3d at 802
    . Thus, the district court
    did not abuse its discretion by admitting the evidence
    of other drug transactions between Harris and Haynes.
    2. Testimony about prior drug deals with Powers and Brown
    The district court also allowed the government to pre-
    sent testimony under Federal Rule of Evidence 404(b)
    about Harris’s drug transactions with Powers and Brown.
    Harris again argues that the district court abused its
    discretion by admitting improper propensity evidence. See
    Fed. R. Evid. 404(b); Simpson, 
    479 F.3d at 497
    . The govern-
    ment counters that the evidence was properly admitted
    because it was not introduced to demonstrate Harris’s
    propensity to sell drugs, but instead to prove his intent,
    knowledge, opportunity, and the absence of mistake. See
    Fed. R. Evid. 404(b); Sebolt, 
    460 F.3d at 916
    .
    As with the other drug transactions between Harris
    and Haynes, evidence that Harris sold drugs to Brown
    was relevant to prove Harris’s intent, see Moore, No.
    07-3445, slip op. at 7-8; Taylor, 
    522 F.3d at 734
    ; Ross, 
    510 F.3d at 713
    , and to prove his knowledge of the drugs
    and firearms recovered, see Best, 
    250 F.3d at 1092
    . It also
    helped establish Harris’s motive to possess the gun. See
    No. 07-2195                                               19
    United States v. Caldwell, 
    423 F.3d 754
    , 759 (7th Cir. 2005);
    United States v. Lloyd, 
    71 F.3d 1256
    , 1264 (7th Cir. 1995).
    Haynes’s testimony about his conversation with Harris
    about prior drug dealing with Brown revealed that
    Harris also needed the firearm for protection from
    Brown’s family. The testimony from Powers and Brown
    was also relevant to rebut the allegations of mistake that
    Harris raised by repeatedly challenging the veracity of
    Haynes’s testimony, and by frequently citing the fact
    that the recordings of the controlled purchases did not
    portray drugs changing hands or any discussion of drugs.
    See Taylor, 
    522 F.3d at 733
    . Powers’s testimony about how
    he and Harris negotiated prices during their drug trans-
    actions by silently passing a cell phone between them
    corroborated and illuminated Haynes’s testimony about
    the controlled purchases and was especially probative
    to prove absence of mistake. Moreover, as the district
    court noted, the evidence that Harris purchased drugs
    from Powers was admissible to establish that Harris
    had the opportunity to make the controlled sales by
    tracing a potential supplier of the drugs sold to Haynes.
    The testimony from Powers and Brown was also
    “similar enough and close enough in time” to the charged
    conduct. Like Haynes, Powers and Brown also testified
    about drug deals involving cocaine within two years of
    the charged conduct. See Ross, 
    510 F.3d at 713
    ; Ruiz, 
    178 F.3d at 880-81
    . The evidence was also sufficient to sup-
    port a jury finding that Harris engaged in the prior drug
    transactions with Powers and Brown. See Mallett, 
    496 F.3d at 802
    . Finally, the substantial probative value of
    the testimony from Powers and Brown on the issues of
    intent, absence of mistake, knowledge, motive, and op-
    portunity greatly outweighed any potential unfair preju-
    dice, especially in light of the district court’s time-frame
    20                                              No. 07-2195
    limitation and diligent, unopposed limiting instructions.
    See Moore, No. 07-3445, slip op. at 9; Mallett, 
    496 F.3d at 802
    ; United States v. Whitlow, 
    381 F.3d 679
    , 686 (7th Cir.
    2004). The district court did not abuse its discretion by
    admitting testimony about Powers’s and Brown’s drug
    transactions with Harris.
    3. Testimony about Harris’s luxury vehicles
    Harris claims that the district court improperly admit-
    ted evidence that he drove numerous luxury vehicles
    because the evidence was irrelevant and unfairly prej-
    udicial. Under Federal Rule of Evidence 401, evidence
    is relevant if it has “any tendency to make the existence
    of any fact that is of consequence to the determination of
    the action more probable or less probable than it would
    be without the evidence.” Fed. R. Evid. 401. Evidence
    of unexplained wealth, such as the testimony about
    Harris’s luxury vehicles, is admissible as relevant cir-
    cumstantial evidence of drug trafficking if the unex-
    plained wealth was acquired contemporaneously with
    the alleged drug trafficking, if the wealth creates an
    inference that the defendant was involved in drug traf-
    ficking, and if the government presents evidence that
    the wealth was not obtained through legitimate means.
    United States v. Carrera, 
    259 F.3d 818
    , 829 (7th Cir. 2001);
    see also United States v. Smith, 
    308 F.3d 726
    , 737 (7th Cir.
    2002) (“[E]vidence of an unexplained, lavish lifestyle is
    probative of the existence of income derived from a
    drug conspiracy.”); United States v. Penny, 
    60 F.3d 1257
    ,
    1263 (7th Cir. 1995).
    The district court articulated the proper legal standard
    in its ruling on Harris’s motion in limine, stating that the
    No. 07-2195                                            21
    vehicle evidence would “be relevant to show an unac-
    counted for source of income if the Government is able
    to introduce other evidence that the defendant lacked a
    source of income.” And the government laid its founda-
    tion through Harris’s girlfriend, who testified that
    Harris was not employed from 2003 through 2006. The
    evidence of luxury vehicles had some probative value,
    especially considering that these vehicles were not regis-
    tered to Harris but to his relatives and acquaintances—
    including his six-year-old son. We do not believe the
    vehicle evidence was unfairly prejudicial, and the dis-
    trict court did not abuse its discretion by allowing the
    government to present the evidence. See Wantuch, 
    525 F.3d at 518
    .
    4. Testimony about the uncharged .22 revolver and 9mm
    ammunition
    Harris also objects to the district court’s admission of
    evidence regarding the .22 revolver and 9mm ammuni-
    tion that officers recovered from his girlfriend’s resid-
    ence, but for which he was not charged. We can quickly
    dispose of this final evidentiary challenge because the
    evidence was admissible under Rule 404(b). See Ross,
    
    510 F.3d at 713
    . The government was entitled to introduce
    evidence of the .22 revolver and the 9mm ammunition
    to rebut Harris’s defense that the 9mm pistol found at
    his house was not his—the ammunition was particularly
    probative on this point. See United States v. Tylkowski, 
    9 F.3d 1255
    , 1262 (7th Cir. 1993) (“[T]he government was
    entitled to introduce the challenged weapons to rebut
    Richard’s claim that [he] lacked the requisite knowledge
    of the contents of the sealed boxes.”). And as with the
    testimony of other drug deals, the .22 revolver and the
    22                                             No. 07-2195
    9mm ammunition were also relevant to prove that
    Harris intended to distribute the drugs found during the
    searches. The evidence was found in the same search as
    the drugs and weapons that supported the charges in the
    indictment, and the evidence clearly supported a jury
    verdict on a felon-in-possession count. We agree with
    the district court that the addition of testimony about
    the second gun and ammunition did not add unfair
    prejudice, and the district court did not abuse its discre-
    tion in admitting the evidence. Dennis, 
    497 F.3d at 768
    .
    B. The government’s closing argument
    Harris did not object to the government’s closing argu-
    ment at trial, so we review the prosecutor’s comments
    for plain error. See United States v. James, 
    487 F.3d 518
    ,
    525 (7th Cir. 2007). Harris claims that the prosecutor’s
    comments referring to Harris’s prior dealings with
    Haynes, Powers, and Brown, as well as the prosecutor’s
    characterization of the evidence, “demonstrate[ ] that the
    government used this evidence for different reasons
    than originally claimed; there is no mention here of
    intent or plan.” We disagree. The prosecutor’s closing
    argument fairly commented on the evidence to refute the
    closing argument by Harris’s counsel, which repeatedly
    claimed that Harris did not have the requisite intent or
    knowledge to be convicted on any of the indicted charges.
    And the prosecutor explained to the jury that it could
    only consider the prior transactions for limited purposes,
    as instructed by the district court. The district court did
    not clearly err by allowing the prosecutor to comment
    on admissible evidence that rebutted the defense’s trial
    theories. See 
    id.
    No. 07-2195                                                23
    C. The propriety of Harris’s sentence after Kimbrough and
    Taylor
    Finally, we turn to Harris’s sentence. At our request,
    Harris submitted a supplemental memorandum on the
    viability of his sentence after Kimbrough v. United States,
    
    128 S. Ct. 558
     (2007), and United States v. Taylor, 
    520 F.3d 746
     (7th Cir. 2008), in which Harris argued that his
    sentence was invalid. The government claims that Harris
    waived any argument about the legitimacy of his sen-
    tence by failing to raise it in his appellate briefs or at
    oral argument. See Valentine v. City of Chicago, 
    452 F.3d 670
    ,
    680 n.1 (7th Cir. 2006); Szczesny v. Ashcroft, 
    358 F.3d 464
    ,
    465 (7th Cir. 2004). Initially objecting to a criminal sen-
    tence in a post-argument supplemental memorandum
    does seem like a waiver. See Valentine, 
    452 F.3d at
    680 n.1.
    Nevertheless, because the issue was raised subsequent
    to oral argument at our request, and because this issue
    will likely impact future cases, we will address it on the
    merits.
    In Kimbrough, the Supreme Court held that a district
    court may reasonably depart under 
    18 U.S.C. § 3553
    (a)
    from the 100-to-1 crack cocaine to powder cocaine ratio
    prescribed by § 2D1.1 of the United States Sentencing
    Guidelines. 
    128 S. Ct. at 575
    . In order to address “the
    recurring issue of the proper treatment of crack sen-
    tencing appeals that were pending when the Supreme
    Court decided Kimbrough,” in United States v. Taylor we
    outlined a new approach for defendants who had failed to
    object to a district court’s pre-Kimbrough sentence under
    the guidelines. See 
    520 F.3d at 746
    .
    Although Harris was convicted for distributing crack
    cocaine, this case presents a different issue entirely. Harris
    was not sentenced under § 2D1.1 for the amount of crack
    24                                               No. 07-2195
    cocaine he distributed, but rather under § 4B1.1 as a
    career offender. Section 2D1.1 employs a drug-quantity
    table to provide an offense level that is based on the
    amount of drugs at issue. In contrast, § 4B1.1 correlates
    offense levels and sentencing ranges with the gravity of
    the crime by incorporating the statutory maximum sen-
    tence for the underlying offense. See U.S.S.G.
    § 4B1.1(B)(1)(A). For example, under § 4B1.1, a defendant
    is assigned an offense level of 37 if his crime carries
    a statutory maximum sentence of life. See id. Thus,
    § 4B1.1 does not inherently prescribe different punish-
    ments for crimes involving crack cocaine than it does for
    crimes involving powder cocaine. To the extent that a
    sentencing disparity might occur under § 4B1.1 based
    upon the type of cocaine involved, it does not result
    from the now-advisory drug quantity table, but is the
    product of a discrepancy created by statute. See, e.g., 
    21 U.S.C. § 841
    (b) (setting the same statutory minima and
    maxima for 5 kg of powder cocaine and 50 g of crack
    cocaine).
    While the sentencing guidelines may be only advisory
    for district judges, congressional legislation is not. As
    the First Circuit has explained, “the decision in
    Kimbrough—though doubtless important in some cases—is
    only of academic interest [in a case arising under the
    career offender guideline].” United States v. Jimenez, 
    512 F.3d 1
    , 9 (1st Cir. 2007); see also United States v. Clay, 
    524 F.3d 877
    , 878-79 (8th Cir. 2008) (“Although the recent
    amendments to the sentencing guidelines lowered the
    offense levels associated with crack in the drug quantity
    table in U.S.S.G. § 2D1.1, they did not change the career
    offender provision in § 4B1.1 . . . .”); United States v.
    Crawford, 
    520 F.3d 1072
    , 1075 (9th Cir. 2008). But our
    No. 07-2195                                                25
    discussion should not be read to suggest that § 4B1.1 is
    any less advisory for a district judge than the other sen-
    tencing guidelines. Cf. United States v. Martin, 
    520 F.3d 87
    , 96 (1st Cir. 2008) (upholding district court’s decision
    to depart from career-offender guideline); United States
    v. Sanchez, 
    517 F.3d 651
    , 663 (2d Cir. 2008) (“[W]hile the
    sentencing statute expressly directs the district court to
    ‘consider’ the ‘sentencing range established for . . . the
    applicable category of defendant as set forth in the guide-
    lines’ . . . it does not instruct the court to impose such
    a sentence.” (quoting 
    18 U.S.C. § 3553
    (a)(4)(A))).
    We follow our sister circuits and clarify: a sentence
    entered under the career offender guideline, § 4B1.1,
    raises no Kimbrough problem because to the extent it
    treats crack cocaine differently from powder cocaine, the
    disparity arises from a statute, not from the advisory
    guidelines. Therefore, the Kimbrough decision in no way
    affected Harris’s sentence, so we will affirm the sen-
    tence given by the district court. See United States v. White,
    
    519 F.3d 342
    , 349 (7th Cir. 2008).
    III. CONCLUSION
    We AFFIRM the judgment of conviction, and the sen-
    tence of the district court.
