Best place to sell used games?

Any of you know the best place to sell old video games? I have a bunch of old ps3 games and gamestop is offering like $1-5 for each. Wondering if some of you gamers know of a better spot. Thanks. I'm trying to offset the price for smash bros on the wii u. Phone Post 3.0

I was hoping for a different website, something like a gamestop but that pays a little more for used games. Maybe a website like that didn't exist? Phone Post 3.0
