Recently I asked a simple question about a dress I was interested in but never got a response...that was kinda rude but I got over it fast since it was overpriced anyway. That's the only problem I've had as a (potential) buyer, thankfully.
Now as a seller, I have a recurring headache, as I'm sure many sellers do, in the form of non paying bidders. Whole 'nother can of irritating, frustrating worms there.
Anyway...yeah Ebay can be a real pain.
