I read through the ebay posting, and the seller talks about Buy it Now having free shipping, but the listing doesn't show a Buy it Now cost. Also he talks about International buyers would have to pay more for shipping, but only lists the USA for buyers.
I have made the mistake of bidding on listings that don't say they will ship worldwide, and lost out. There was one occasion when I had bid higher than the eventual selling price, and still didn't get it, because of that listing, which was really frustrating, especially as I had emailed the seller, who had agreed to send it to me if I won the auction. Now I have to not only get the agreement of a seller if I am prepared to pay the higher shippinig costs, but I also have to persuade them to alter their listing for that item, to read Worldwide.
