Have been told ebay will now hold your money til you have received the goods and are happy with them then they release the payment to the seller, if not happy they will return your money to your paypal account upon seller receiving the back the goods...
Cant get to shipping address screen to change address to a US address, as seller doesn't post overseas. Can't contact seller as it just goes to their questions & answers, click other still no question box - should I just give up?
