[quote name='Brian9824']Almost no retailer lets you return open hardware. Think about it. If you buy a console, play it for a week and then decide to return it what are they supposed to do with it? They don't sell used consoles and they can't sell it as new[/QUOTE]
Actually in my experience not being able to return hardware to a retailer is the exception and not the norm. Indeed it could be argued that easy, instant returns are one thing that B&M stores hold to their advantage over online retailers. For someone who is a little on the fence about buying something, the reassurance of an instant and easy return at a B&M store can sway them to buy there instead of going online.
As two of us have shown, there is no wording on BB's return policy that would prohibit the return of a console. Gamestop OTOH, looks like you can't return much of anything there. I think I had a little difficulty returning a piano black PSP 2000 I bought from TRU once, I had some legitimate cause to return it but they would only let me exchange it for an identical one, on which they broke the seal before giving it to me. Except they did not have the same PSP in stock anymore so they changed it out for the Star Wars white one.
I don't know 100% as I have never worked retail but AFAIK the stores either have some mechanism with the distributors to send back opened/returned merchandise that can be refurbed and sold as such, or occasionally you see stores holding open box/returned item sales where they can re-sell returned items that are in saleable condition.
I have never seen gaming hardware on the open box tables, but I would bet that such items are pretty hot and would sell really fast.
Why don't people abuse it? I'm sure some do, and for the B&M it's just the cost of doing business. For the rest of us, things like morals and principles tend to get in the way.

Also for many it's not worth fronting the $250-300 needed to "rent" a console from BB to play the latest game.
