I live in United Arab Emirates and have bought and sold many things on Audiogon sometimes to/from the US and others to Europe. No problems, the same rules apply. Sometimes sellers worry about customs. You see the customs are the responsibility of the buyer. So the most that you would do in enclose an invoice describing the item and the market price for it. And if you want to help the buyer reduce the cost of customs you should reduce that value.
Any problems selling equipment outside of USA?
I've recently been contacted by a British man about buying my amplifier through Escrow.com. What kind of problems are there in shipping and completing the sale successfully? What role does Customs play? Does anyone have experience with this? I'm not sure how safe I feel about this.
