i dont understand why people do things like this, it seems like too much of a hassle to try to return something to a store where you didnt by the game just because you bought the same game for less. If you are saving 5 or even 10 bucks to get the cheaper game, how is it even worth it given how much it costs ion gas to drive to the store you are trying to scam, and wait in line, and then fight traffic again on the way back. All that to save $5 to 10 bucks?
there are much better was to spend, or in this case, scam your time and money
edit
the true scam artist would find a sale like the TRU sale and then buy all the games, or at least half the store, and take them to walmart and say "i got all of these games as presents for graduating and none of them have receipts, and i want to return them."
Now that is how a true scammer operates. take note, i have never returned anything without a receipt, and realize that if people abuse a store's return policy, they will eventually change the policy, as people have said in this thread with tru and target
