By the way, I strongly recommend looking for specific games in store via their website. A couple reasons:
1. Many stores are so disorganized they don't even know they have PSone and 64 games.
2. People that work there horde good games in the back and wait for a sale. If you talk to the manager (or the DM) they will often sell you what isn't on the floor. You just need to call them on it first!
This will give you a little advantage in snagging what little is left. If you have questions about GS/EB, I'm more than happy to help.
