This past week I sold a buddy a few PS1 games (Fear Effect, RE: DC, & Abe's Exoddus). I only charged $3 for RE: DC. He had a gallon of milk, so as part of the deal I got the milk for RE: DC. (I got $ for the others).
What's the weirdest/funniest thing you've ever traded/accepted in trade for games? Yes, I suppose...er, physical activites count.
