Well, look at what you can already do with their trading card program. You could just list cards yourself on eBay, of course. You could drop them off at a shipper to send them off. You could keep them at home while you're waiting for a sale, where I guess they're insured by your renter's/homeowner's insurance. And if you want them graded, you can send them off for that however you like, too.

Or, you can bring your cards into Gamestop, and they'll send them off to get them graded and/or buy them from you, at which point they become inventory for their lootbox. With eBay, you'd be able to do all of that, too, except you'd be selling directly to someone else through a consignment service - more pricing freedom.

And then you could start doing it with things other than cards.
