For retail I don't think you did that bad. I live in an area that doesn't have many pins available, even from a private seller they would probably be asking 2000 plus. If you did over pay you didn't get royally ripped off or anything. I see a lot of posts where prices are discussed and wonder where in the world you can find this or that game at the prices mentioned...
In the end the deal is done, just enjoy your game and have fun!
