Delivery of American orders is guaranteed.

CUSTOMERS OUTSIDE THE UNITED STATES OF AMERICA: Delivery of any order outside the United States is NOT GUARANTEED. For international orders, the service we provide is not delivery. It is packing and addressing the order and consigning it to the post office. That's the best we can offer. Beyond that point we don't know about or control any aspect of the shipment, and are not responsible for ultimate delivery. The problem is that we cannot control whether international parcels are confiscated by your customs service, or lost or stolen or mis-delivered.

There seeming anomalies in this rate chart are based on the very odd structure of certain international postal rates.
Express Mail becomes an attractive choice on larger INTERNATIONAL orders because the airmail and express rates converge as weight increases.
