I don't have tax where I live so a i can't add that. I'm throwing a ballpark estimate at $150? The trade-in stores are very cheap you know. You can always ask them in store and look and prices of any game on the internet.How much money would you get if you sell these systems and games to gamespot?
more than a pawn shop would give you, but not as much as someone local like in a newspaper ad.
