I was at Old Navy tonight and saw they had many games left over from Christmas that are now on clearance. They had Wii, PS3, PSP, and XBOX. I didn't see all the titles but they had Rockband 2, Beatles Rockband and Lego Rockband on clearance for $27.49. Then you can use the $5 off $25 coupon on oldnavyweekly.com making it $22.49. Click on the stripe polo and the jeans underneath it. Then click Eva's face to get the $5 off $25 coupon. Click on the yellow shirt and jeans under it for $10 off $50 (thanks jammas6) if you want more than one.

The store nearest my house didn't have any left but the next town had a bunch so I guess YMMV. (Another poster mentioned their store had them in the manager's office instead of at the register so if you don't see them, ask!)
