If it doesn't sell at this auction, I'll start a new auction and open it up for overseas bidders. But as spihunter mentioned, US Customs can be a b@tch and the delivery times can get crazy. Plus the additional shipping costs deter some bidders.
I got bunch of stuff from UK and China, no problems at ALL. Never got hit with customs fee and it arrived quickly. I do sometimes wonder if they will send me a bill ...
Maybe the problem is with other countries customs, not USA.
