Would the drive really be out of the question?
I mean I know that a 2 hr drive one way isn't exactly pleasant but if you do the only problems you'll face are gas prices and the seller potentially not showing up and having to take a 2 hr drive back home empty handed. But if everything is legitimate then that 2 hr drive home wouldn't feel as bad and youd be going home knowing that you won't have any other worries except for selling the game. If anything take a good friend and make it a little day trip kinda thing.
I once took a 90 mile drive that was 1.5 hrs long to a junkyard (wanted to find spare parts for various car projects) only to find out that the place had long been shut down :/ but since I had gone with my cousin, the drive went pretty well and we hung around the town a bit before heading back. It sucked that our plans failed, but it was also nice to just take the drive and make it into a little mini trip.
