If I was you, I would go online and try to sell/trade. Goozex is a great option, but you need trading tokens or whatever they're called to actually do a trade. You can buy them for a few dollars with a credit card or money order (I'm not exactly sure about the money order, though). The advantage to the site is that a lot of popular games, old or new, go for a lot of points. People are always looking to trade, so I suggest using Goozex if you can.
