I keep hearing people talk about problems on EBAY. My wife buys and sells old garbage Barbie dolls, I hope she doesn't read this. Those stupid dolls are often priced at several hundred to several thousand dollars. She has also bought and sold high end ice skates and horse stuff. I would have to say that she has been a buyer or a seller, more often a buyer, in probably 100-150 , maybe more, actually, transactions. She has never had any sort of problem at all.
She has spent several thousand and recieved that much several time. Never even a hint of a problem.
I think that in general, you are dealing with people just like yourself, would you rip someone off?
The best protection is to check th other participant's feedback, if he has had a history of causing problems, it will be reflected there.
