Hi all, anyone encountered this before? I receive an item that is not the same as what i have bidded. And the seller is asking me to send back the wrong one and he send me the right one. Am i obliged to send the wrong item back and incur the postage myself? I think it's not my fault and why should i incur extra cost for the seller's mistake. Is there a rule in eBay for buyer to send back wrong item to seller? Thanks for your help!
