Have you heard about this great new site? NoLongerNeedIt.com is like a cross between ebay and Craigslist where you can get rid of the stuff you don't want and either sell it for cash or trade it for things you do want!
Now I know we all got a few gifts at Christmas that you have absolutely no idea where they came from and you can't return them, but you don't really want them... Well list them for free on this site and get some cash or make a list of things you would trade the items for! Its also great because you can set up a local meet-up or you can arrange shipping and payment from the buyer. The best of both worlds!
