I went and checked out this store that is new in the area called Five Below, and they had a software section where all the games were five dollars (everything in the store is $5 or less).

Picked up Tom Clancy's HAWX for $5.

They also had Bully, Godfather 2, Quake Wars: Enemy Territory, A double pack of Splinter Cell games (looked like the older ones). They had some 360, PS2, and Wii games too, but I didn't pay to much attention to them.

Five Below seems to be an East Coast store. http://www.fivebelow.com/ YMMV. They had some interesting games for $5 though.
