Return shipping and the time to ship it ... and the time spent on that barrage of emails. What gets me most is when ... nevermind, it's too early to get bent about effing eBay. I recently had a non paying bidder charge leveled at me. I told them I had a receipt and I had the item. That led them to conclude that I in fact did not pay. But I have a receipt. Seller says you didn't pay ... that means you didn't pay. Maybe I shouldn't have called them retarded.
