Before making your items available to international bidders, remember that if a buyer "discovers" any fault with an item eBay will accept their word for this, and probably require you to arrange and pay for the international return as well as refunding them in full.
We have heard from sellers who have found this so difficult and costly to arrange that they have simply refunded the buyer and let them keep the item. Suspicion has been voiced that some overseas buyers are now inventing faults in the hope of getting their item for nothing.
