[quote name='chargeup45']You would have to return them all without a receipt, because the promo won't be in the computer by the time the games launch. I'd feel pretty guilty about doing this one though.[/QUOTE]
Return 2 games with the gift receipt and keep the one you got free at home. Why can't you return the 2 you paid for and pay the difference to get something else? Use some nice story about getting them as gift for your nephew or lil brother but now the person got rid of his PS2 to buy a 360. If they go for it sell the game new on Ebay or trade it for $35 or $30 at GR. That would be $90+tax for 2 $60 games. (100, return 2 and pay $20, minus at least $30 credit at GR or cash on Ebay for the third game).
