The act of going to gamestop and buying(renting) a used game and returning it within 7 days for a full refund.
I bought Halo Reach with the intent of doing a gamestop rental. I wasn't able to finish it, but it was the last day to return it for a refund. So I returned it. Went to a different gamestop and "rented" another copy. Beat it the next day and returned that copy for a full refund.
