The typical scam that's been tried on me is a buyer with a confirmed location in Europe says that he will be visiting the U.S. and would like to save on shipping by picking up the item there. They win the auction, give a U.S. address and ask to have it shipped there. Usually they just give the address, not the explanation and hope you'll just ship it there. When you discover the changed address they give you the story. The finale is you ship the goods, they receive them, the receipt is signed for & confirmed and then they get their money back because they say they never received it, you didn't ship to the confirmed address, someone else must have received the goods, claw back the cash. I've never fallen for it.
