I went to game yesterday and bought a few games with a gift card. The shop assistant tried to tempt me to have deus ex as a preowned game for £2 less than it was new. i told him no, I wanted a new game. However after this he came back to the desk with what appeared to be a new game though it went through the till as preowned.
Whether they were doing something dodgy and selling new games as preowned or this guy was just forcing me to buy preowned I don't know. But to avoid causing a kerfuffle I just took the "preowned" game.
Either way it looks like the game stores have gone really down hill from a couple of years ago. Maybe the next gen consoles will give them a boost in 2013.
