On the subject of wrong addresses, what can I do if I order using checkout to have item sent to a relative in another part of the country,  and the seller ignores the 'post to' address and sends it to my registered address? If I receive it here, I then have to pay postage to send it to the address it should have been sent to?

Why do ebay even show the seller the registered address if the buyer has opted for another address at checkout?
