I checked it out the last time they did this and I wasn't impressed with their prices. Even with a 20% discount there weren't many (any?) good deals to be found, especially considering that, unlike visiting a local Gamestop, for example, you have no idea what you are getting. Both content and condition. Sure, they may usually be in good shape and complete (yes? no?), but when it isn't it isn't and you have no way to tell ahead of time. So... they need to have some pretty good prices, and they don't.
