Wait so he has to pull his money out if the game comes out, before he actually gets charged for it? If he waits too late then he has to buy it and gamestop gets a cut if he returns it.
So OP is actually a genius. Except if you put money in a bank, it grows some money. Also it's insured, I wonder how stringent the protections are if GameStop was to go bankrupt and take the money with them.
No, he's stupid. Gamestop could change their policies at any time making deposit refunds store credit only. Gamestop could go under and he wouldn't be FDIC covered. Can't emphasize enough the store credit policy switch which they'd do just in response to him.
There's none. They would owe him money, so he'd have to get in line with all the other creditors to request that the court prioritize his debt over someone else's.
