Just looked at that sight. If you can sell them for those prices, go for it. Some of the game traders in my area sell for cheaper. There was a couple that were flip flopped (Mario 3 says $14, I think I've seen it for 20). Contra is not $26. $15 maybe. Mike Tyson punchout same. Friday the 13th is about $7-8, not 13. Just a few I saw.
