Best way to get rid of FF VII (black label) and GTA trilogy (XBox)?

I have my original black label copy of Final Fantasy VII that I've had since it was originally released and was holding onto it for nostalgic purposes but don't really need it anymore, especially since I can get it on PSN for $10 and was wondering what the best way to get rid of it would be?

Are EBay and Amazon Marketplace my best options? Their commissions are kind of ridiculous so I was hoping there are other ways. I've put it on Craigslist but all I get is people from out of town and that's kind of shady.

I also have the GTA trilogy on the original XBox that I don't need anymore but the case is really worn. I bought it used a few years ago to play through them all again before GTA IV came out.

What's a fair price to get for these without anyone being ripped off?

One of the best ways might just be to sell it through CAG, at least then you only have to pay the Paypal fee (no eBay/Amazon rates).

CAG is definitely a good bet. Throw it in the market place and also make a thread in the trading forum. Keep it bumped and see what comes of it. Search ebay for what you have, and look at the completed listing to get an idea of the value.
