It's all shipping fees.

It's so bad that "Reshippers" are increadibly popular here (in Australia). They have a US address so you can ship Amazon stuff there, and then either do a bulk shipment of multiple orders to Australia, or else just accept their shipping charges (which are usually 50% of what Amazon charges).
