Just wanted to quick share a recent experience I had with an eBay purchase and their '
Authenticity Guarantee' program (which is not an optional service, as I'm sure you know). I ordered a pair of shoes but realized immediately they were not the size I wanted (they were size 13 but were listed under size 11 search filter). Literally within seconds of pushing the purchase through, I contacted the seller to ask if he could cancel the order. He apparently didn't check his messages and just went ahead and sent them in for 'authorization'. I tried contacting eBay at this stage to have the order cancelled, but was told it couldn't be cancelled once it was sent in. Then when I received them I, obviously, was looking to return them but was informed by eBay that "items covered by
Authenticity Guarantee can’t be returned." So, lesson learned, I guess. Make sure you REALLY make sure you got the right stuff before pushing that 'purchase' button now on eBay.
