Had a hit at a St. Louis area mall Gamestop about 3 weeks ago. Got a Deus Ex for free (rang it up but the cashier just paid the penny - nice). They did mention that "someone must have missed these," unfortunately.

Also tried a Collinsville Gamestop and got nothing. Only had a few really new guides on the floor and the ones that he told me were in the back were newer-ish as well.
