CC ads are no good anymore and no one will price match the next two or so that have already been printed. Your only bet is the $10 off coupon from 2Ksports.com before the end of the month, or wait until Gamestop has an email coupon for 20% off (30% off with Edge) used game for either the PS3 or 360 and get a copy for $38.50 plus tax.
FYI the email coupon this week (good until close of business Thursday) is off used PS3 games.
