Facebook Marketplace, to dedicated groups. I don't like using Facebook, but it's selling pretty quickly everytime.
Otherwise, there's a FLGS that does used games sales every season. You bring your games and if they sell, you get credits to use at the store.
Same idea: restore a backup to the automatically selected database in the drop down instead of a new database (Thanks Sql Server 2000 entreprise manager!)

Fun times.
