I have a friend that has worked at gamestop for years. He says they don't actually make money on the new games. They pay pretty much the same price for them you do. They make their profit on used ones. Thatt's why the prices are jacked up so high.
lol he said you can buy a game, take the game out, go back to the store, tell them there was no game in your case, and they have to give you a new one. Nothing they can do about it. You can later return the new game for a refund and keep the stolen one lawlawlawlawlawlawl.
Unfortunately I don't like to rip people off, but damn if I did I'd have a lot of free games right now.
