i just went to target and did this. i was buying newly released so i thought i'd try. got the rainchecks when i bought the dvds, took the dvds to my car, came back, and got 3 games. the raincheck form was right by where the game would be. i got 3 and they had no problem. went to substitute the games and again they had no problem. i got mechwarrior 4, warcraft 3 battle chest, and call of duty for a total of $43.
