Definitely. Had a couple of issues last year.  One is on another forum, so wont go into. Had one on another ebay site we have where the buyer purchased from our webstore/freight free a couple of times over a month and then two weeks later from our Ebay site/plus freight. He knew the items were cheaper on our webstore before the Ebay purchase. He claimed damage in transit on the Ebay purchase so we reshipped. And he claimed again for damage in transit on the reship. Our packaging is heavy duty and we have never previously had any claims at all EVER, so two, days apart, was outstanding to say the least. We requested images for both. Fortunately we were able to show the hole in the double packaging (internal bag and external envelope) were too small for the items to have fallen out as he claimed (and the product is solid metal and indestructable). Simply a case of trying to 'double dip' because he figured ebay would either refund him or he'd get a freebe (which he did).

Buyer was using a psuedonym as well. Blocked now.
