I usually fall victim to gamestop and thier low ball prices on used games. I was cringing at the thought of trading my games in for a new game I wanted. I checked the prices at gamestop and acutally walked out without my game.
I did a search on google and found these guys, I check the prices and it was almost double what gamestop was giving me. I highly reccommend checking these guys out. They also ended up buying a N64 which I have been looking for!
