best place to trade-in mario party 3 and mario tennis?

Hard to say, I'm guessing that most places like GStop/EB/GRush/GCrazy will give you nothing more than a dollar or 2 on each game. If you have an eBay account, you could sell them for about $8-$10 each. Maybe someone else can answer it completely :)
