Works for international shipping as well. Shipped a Castle Whiterock boxed set to Norway a couple of weeks ago.
USPS quoted me the ridiculous price of $67.15, but paypal ended up charging me the ridiculous price of $63.79. I had to ask the buyer if he was sure he wanted it, but he was unfazed. And happy to get his big shipping refund of $3.36.
