I'm sure they're not sold on commission, so it's a huge outlay to stock every store with dozens. Best Buy can probably afford that, and afford the shipping between stores if needed, not to mention that they have a lot more storage space per store. Gamestop probably can't afford it. That doesn't mean that it's not a lousy store, though. Hell, they both are, but it's not like Gamestop is some mom-and-pop store (or even mom-and-pop franchise) that you ought to support. It's a corporation just like Best Buy.
