Website's that buys back console games or DVDs?

I had great success with selling back books, and now since I still am looking for a little more extra cash until I get a new job, I was wondering if there were any websites which buy back games or DVDs? Obviously I get a few results when typing in google, but I'm not sure which, if any, are actually trustworthy sites. Anyone have any suggestions? Also, before suggesting places like gamestop, please be mindful that I live in a rather small town that doesn't have an abundance of places like that.
