I've said it before, and will say it again, just as others have, the buyer has all the power on ebay. Sellers have little recourse. Does not matter what the listing says, it means almost nothing to the arbitrators. They rule in favor of the buyer most of the time. I bet it is over 95 percent. We sold on ebay millions of dollars each year and it became a total hassle that had to be accommodated to survive as our model was built upon ebay sales. After 2 years of putting up with people who took advantage of the ebay ethos, we began to challenge dubious claims of damaged goods, doesn't fit as described, item does not match description, etc. Had success doing this, and gave us the courage to ban repeat offenders. Over time we developed our own website which accounted for 50% of sales at the time I left the company 5 years ago.
I don't buy or sell on ebay. Just ain't worth the hassle to deal with someone in the virtual world as what you see is not who they are.
