I bought two coins from the States and the guy sent it to my PO Box too, but Parcel Force sent me a letter asking me to pick it up or arrange redelivery, not bad! Free redelivery too!! I mainly deal with people in the UK, but US, Australia, France, Belgium, Canada and Germany are frequent customers/sellers to me. I haven't had any major problems with international transactions apart from one to Saudi Arabia... As with Royal Mail, I have quite a few problems with them but I always get my compensation so it's not too bad. I agree with Richard, you can pick up some very rare coins from international sellers as they often cannot ID the coin exactly, it's usually only to a denomination and a monarch so I can pick up a bargain in regards to mint, class, moneyer etc...
