Their address was
International street, town, country and post code, then at the end said "United kingdom"
It was a customer that I'd been speaking to about their order so I do know that it was supposed to be international delivery
I can think of these?-
-Create a custom listing saying "Postage fee to _Country_" and add on the 20c listing fee
-Ask them to send a direct bank transfer with the extra cost, but then I couldn't post until it clears and they need the item by a date they had given me
-Cancel the listing and re do it, charging the listing fee (Do we get ALL fees including the listing fee back when an order is cancelled?)
