Right.
You could probably find a friend or someone in the States to receive it for you.
Otherwise if you want to contact the seller, either make up an American address, or you could go to advance search, then "find a member", type in the seller's ID, then send him a message after selection "this is not about an item". That way the message will go through. Though if he agrees to ship it to you internationally, you'll still have to bid with an American address. If you can't send a message, that means you can't bid with an international address either.
Good luck!
