I BEEN SELLING ON EBAY 12 YEARS,SALES HAVE COME TO A STALL, NO SALES WORST IN 10 YEARS
My advice to you is to "Opt-in" on all your listings. Figure out what categories represent the greatest risk of return to you, then sell those items out and do not sell in those categories any more. Ultimately, you will carve a niche out for yourself. You just can't sell anything and everything on Ebay any more with out take big risks, some people can handle a category with less risk than you while you may be able to handle a category better than others. Find your niche, and Ebay will probably do something to screw that up too, but try to anticipate they're next move.
