I tried ordering one, but when I filled everything in and try to submit it I get the message "One of the products could not be added to your cart..."
The website gives no reason why the order cannot be completed.
Though I suspect that it cannot handle my (dutch) zip code.
(On the other hand it does allow me to select Paypal as a payment method.)
EDIT:
Oops, I just figured out that you need to ring them to place an international order.
I just got confused because they allowed me to enter an international shipping address and even calculated the shipping costs.
It's probably my fault for not understanding that "One of the products could not be added to your cart..." means the same as "Sorry, we do not accept international orders via our website".
