I sold an item on eBay tonight, I have international shipping set to eBay's Global Shipping Programme to save time etc - I don't get many international buyers anyway so it's not usually a problem. However today the buyer contacted me and explained they're from Puerto Rico and eBay won't let them pay for the item - it's saying shipping to their location isn't an option.
How can I proceed from here? I'm assuming the GSP doesn't ship to Puerto Rico (but then why did it let them bid on it? o.O) - I'm happy to send it via normal international post (assuming the buyer is up for it of course - I'd need to get a postage quote) but I'm not sure how to change the listing to reflect that/send them an updated invoice with the postage included/etc. :x Help!
