Why do people sell their second games to stores like gamestop instead of selling them directly to other consumers?

In the case of Gamestop, depending on the special offers going on sometimes it's really worthwhile. A couple years ago I gamed the system there by trading in a bunch of ancient PS2 games that I probably wouldn't have gotten more than $75-$100 for on Ebay and ended up with over $150 in store credit.
