I have been a member of eBay about 20 years as a seller and buyer. I would say sadly that it seems like it has got worse. I have have had a couple experiences lately that some sellers have things for sale, but after making payment they no longer have the item, or on backorder. It's very hard to get your money back. I have had a buyer give me a tracking number and marked item as shipped. Post Office had no record of the tracking number. Also, they will keep moving the delivery date to later. When that day comes they move the dated again. I have had to contact my bank, and report them. If they don't have 100% approval rating, find someone else. I have not had much luck with eBay helping get your money back.
