Seller Beware. I shipped a perfectly good playstation game system to Marianne Alwaque-Buffo TACOMA, WA. Marianne claimed it didn't work and then shipped back her old broken system to me. I opened a claim against her. Ebay made me pay all fees, didn't allow me to leave negative feedback to warn other sellers of this fraud. How does ebay protect sellers? Seems like anyone can go on their site and steal whatever they want. And ebay is protecting their company and the buyer by not allowing negative feedback. Then they look like they are a reputable place to do business. Sincere feedback stating information about the sale should not be regulated. I understand it may go both ways but let others determine who is telling the truth. Terrible service by ebay. Will not do business with again.
