I'm trying to sell all my DVDs. Where can I find the most fair price?

I have about 200 or so DVDs I want to sell. I sold some of the here but the prices seem rock-bottom. So, I set one box-set up to sell on Amazon, but I have to go to the UPS store/pack it up, etc. The idea behind that is that they list it used, but I only get money when someone buys it, Amazon gets a cut, and it could take a long time to actually sell it. Maybe there’s something I’m missing? I’m happy as hell to get rid of them; I don’t expect to get rich off of them, but I’m trying to de-clutter and generally just get rid of my excess crap. I’m sure someone has experience doing this. So: fair price/easy shipping/relatively swift payment…
