Just to clarify a few things from some of the replies above from those who have not sold on eBay before.
An eBay seller cannot leave negative feedback for a buyer. The was changed about five years ago (maybe longer), after a large number of sellers were using negative feedback as retaliation against buyers who left the seller negative feedback. Or, would tell the buyer of a defective item that if they leave negative feedback then he/she will do the same. A lot of buyers would not leave negative feedback for a bad seller in order to keep from getting negative feedback themselves. So, a seller cannot leave negative feedback for anything no matter how much the buyer deserves it. Having said that, I like the rule myself because it weeded out a lot of sellers who were threatening buyers with negative feedback after selling them not as described items.
