eBay Inc EBAY.O Failure to honor return policies Powhatan Virginia

Customer had buyer remorse as they didn't realize All in One Computer they purchased didn't come with touscreen and internal speakers which were not advertised on listing.  We offered to buy them speakers and also provide them courtesy credit but they declined.  We urged them to package it up properly before sending it back.  Our return policy allowed for buyer remorse returns with refund being less shipping cost and any damage found.  eBay allowed customer to return All in One desktop computer with pre-paid label we were charged for.  All in One desktop came back completely shattered to pieces as customer did not package it back up properly at all as they left hard objects pressed against the screen and didn't bother to make sure packaging fit around product like it came to them with.  Customer did not wish to be assessed restocking fee and case was escalated and eBay provided full refund.  For buyer remorse returns, seller should have option to enforce their return policy.  Company loss was $120 shipping each way plus AIO desktops is destroyed and only internal parts might be recoverable so total losses are approaching $1,000.  Amazon is very bad about allowing customers to return anything and everything at loss to seller but at least they will allow sellers to enforce their return policy for orders seller fulfills when it is buyer remorse not not as described for the return reason.  I would warn and advise new and existing sellers alike to be very careful when selling expensive merchandise on eBay as their return policies are becoming very reseller unfriendly - much more so than any other platform we have witnessed including even Amazon.  It is impossible to pay bills and salaries when subjected to such huge losses.  UPS won't even accept the damage claim since the negligence in packaging was so obvious.  This should not be cost of business for sellers to endure.  eBay as all marketplaces should arbitrate fairly.
