[*** MISUSE OF BUYER PROTECTION ***]
This one still makes me laugh. I sold the buyer a 1968 Topps yellow-back; the description included very high resolution pictures, there was no doubt at all what the winning bidder would be getting. Upon receiving the card, somehow he got the idea that the back wasn't "yellow enough". To this day, I have no idea what the hell he was talking about. He ultimately won a case, naturally (screw you eGay), and I had to refund him the purchase amount upon receiving the returned item. After receiving a full refund for an item that didn't have anything wrong with it to begin with, he left negative feedback!
