The items I sell aren't even sealed in the retail package, they are either in a re-sealable retail poly, or just in a retail cardboard box (unsealed but closed). But 4/5 times they come back with the boxes/polys all torn up or totally missing. Many times clothing tags are missing. These all make the returned items useless to me. If I fight these, the buyer will eventually win if they know how ebay works, right?
