Tong C. Park appeals the sentence imposed following her guilty jalea to conspira *464 cy to traffic in counterfeit goods and trafficking in counterfeit goods. She argues that (1) the district court misapplied U.S.S.G § 2B5.3 and (2) her within-guidelines sentence was substantively unreasonable. We affirm.

We review de novo the district court’s interpretation and application of the Sentencing Guidelines and review its factual findings for clear error. United States v. Yi, 460 F.3d 623, 635 (5th Cir. 2006). Based on expert testimony that the infringing items would have appeared to a reasonably informed purchaser to be identical or substantially equivalent to the infringed items, the record supports a conclusion that the district court did not clearly err in using the retail value of the infringed items to calculate Park’s offense level. See § 2B5.3, cmt. (n.2(A)(i)); see United States v. Jackson, 453 F.3d 302, 308 n. 11 (5th Cir. 2006).

We review the substantive reasonableness of Park’s sentence for an abuse of discretion. Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). A discretionary sentence imposed within a properly calculated guidelines range is presumptively reasonable. Rita v. United States, 551 U.S. 338, 347, 127 S.Ct. 2456, 168 L.Ed.2d 203 (2007). The district court refused to consider a downward variance from the advisory range because Park had failed to heed repeated warnings by law enforcement regarding her trafficking in counterfeit goods. See 18 U.S.C. § 3553(a)(2)(A). “[T]he sentencing judge is in a superior position to find facts and judge their import under § 3553(a) with respect to a particular defendant.” United States v. Campos-Maldonado, 531 F.3d 337, 339 (5th Cir.), cert. denied, — U.S.-, 129 S.Ct. 328, 172 L.Ed.2d 236 (2008). Park’s disagreement with the propriety of the sentence imposed does not suffice to rebut the presumption of reasonableness that attaches to a within-guidelines sentence. Cf. United States v. Gomez-Herrera, 523 F.3d 554, 565-66 (5th Cir.), cert. denied, — U.S.-, 129 S.Ct. 624, 172 L.Ed.2d 617 (2008); United States v. Rodriguez, 523 F.3d 519, 526 (5th Cir.), cert. denied, — U.S.-, 129 S.Ct. 624, 172 L.Ed.2d 616 (2008).

AFFIRMED.
