I'm selling some of my s2 stuff I have left over on ebay and I keep getting "hi will you post to malta/greece/denmark etc" I state in bold capital leters UK only in all my auctions

the current highest bidder on one item has already msg'd me from denmark and I said I would not send it there. what should I do? I am not spending extra to post it to this muppet. I've relisted it 3 times!
