Anyone who has previously returned a product purchased on eBay has always received the full purchase price back. How among other things t3n reports, that will probably change in the future. Sellers with a spotless profile or above average status will have the option to retain part of the amount in the future.
So if you send something back on eBay, you have to reckon with not getting the full price back – up to 50 percent. The background: eBay wants to protect sellers who have often been victims of abuse of the return policy in the past. Purchased products were often returned broken or not in full.
