I can't seem to find it anywhere, and I don't want to create a new thread for it...
Has no one mentioned the B1G1 40% off SAVE40 code yet? http://www.gamestop.com/gs/b1g140/
Even with the jacked up prices, B2G1 free is a little bit of a better deal.
2 $60 games - B1G1 40% off = $98 + tax
2 $55 used games - EDGE 10% - B1G1 40% off = about $79 + tax
3 $55 used games - EDGE 10% - B2G1 Free = $99 + tax
So for an extra $20, you get a 3rd full priced game.
