When you list an item on eBay,
as I'm sure you are aware, you are asked to select the territories you ship to (by default its set as UK only). So although its best to state it in the listing itself, if you didn't select the US as one of the territories you ship to they shouldn't of purchased the item.
I wouldn't expect a great deal of help from eBay on the matter. Just explain the situation to the customer, they are in the wrong at the end of the day. Refund them in full and go your separate ways.
