I went to gamestop yesterday and bought saints row(360) 24.99 Call of duty 2(360) 19.99 and prey(360) for free. I went back to the gamestop just a few minutes ago. I had i thought of some better games i could get and wanted to return those those 3 i just named to you. When i was returning them *READ CAREFULLY, HERE IS WHERE I FOUND THE FLAW* the dude behind the counter said that i get 45.00 dollars back but since on the receit it says i payed 00.00 for prey i get to keep it since that was the free game. Then he said wow you just figured out the flaw and then he laughed. BAM! there you go. I took my 45 dollars over to the other gamestop down the road and bought back the SAME 2 GAMES and got prey for free again. Now i have saints row, call of duty 2, and 2 preys.
