I have someone from the Canary Islands having problems paying for an item I'm selling, I'm in the UK and allow international shipping, they say Ebay doesn't include the Canary Islands as part of their international shipping program, which maybe right but this is fine because the buyer is willing to pay me for the postage anyway. Now what about me asking the buyer for their email address so I can send them an invoice for the item sold plus the P&P cost?
