This is unrelated to the OP question; but, I know of an individual that somewhat frequently buys overseas. A concern is legitimacy of the seller. This person will ask the potential foreign seller to hold his passport up next to the item being sold and take a picture and email it to him. This quickly separates the legit sellers from the non-legit.
The person I am thinking of bought an expensive pre-amp from Germany this way.
Lots of scammers online nowadays.
