Their money back guarantee is worthless. I purchased a part from one of their highest rated sellers and when it arrived it didn't fit my car. So I contacted the seller to return it and the seller told me to take it to any shipper I wanted to and get a tracking number and receipt for the cost of shipping it back to them and they would refund me the cost of the part and the shipping when they received the part at their facility. The part cost $44 and the shipping cost $102 so I thought it was kind of stupid of them to have me ship it back to them rather than just throwing it away.Well I found out why they had me pay for the shipping it's because they had no intention of refunding me the shipping costs. And when I asked eBay to step in and help me they told me it was my fault for listening to the seller and following his instructions instead of reading all the policies that eBay has. But they could put the policy that buyers should "NEVER" pay for shipping in big letters everywhere, instead of telling the buyers to contact the obviously sneaky dishonest buyers for returns so they can take advantage of us. eBay claims you don't have to worry about getting taken advantage of that they guarantee your money is protected, well I'm calling a big BS on that. The seller that ripped me off is still doing business like usual ( lying and cheating his buyers) and eBay is still making money off of the dishonest sneaky sellers they rate so high.
