I got burned by an eBay seller a few years back. I paid with my AmEx through PayPal and neither would refund my money when the bag turned out to be obviously fake. AmEx said they couldn't do anything and then PayPal said that they wouldn't do anything b/c the seller did send me the item. Now I've found another bag that I am pretty sure is authentic (it was authenticated on tPF as well) but I can't get the other incident out of my mind. This bag is quite a bit more than the other fake (this one is around $800.) The only way for me to get this bag is through eBay since it isn't made anymore. What can I do to protect myself so history doesn't repeat itself?
