I know because -
a) I live in Australia.
b) I have made several hefty Tom Bihn orders - throw in an Ego, a cadet, a couple cafe bags and some pouches etc and the shipping cost hardly hurts at all. The current exchange rate is a help - in 2002, a Ego would have cost a lot more.
(we sell ring bound notebooks - oddly enough we get a non trivial number of orders from Europe, and even some from the US.)
