content: Yea I agree with you on the cargo ship. It's rare that you actually have to move single packages through the air. That's why shipping something say the size of a hard drive from America to Australia can run you $60, even with the cheapest post options. (Unless you can fight a carrier that will put your box onto a cargo freighter that takes 3 to 4 weeks to make it to its destination.) Most freight is more efficiently transported by boat, as the 3 ~ 6 week delay isn't that big a deal for large chunks of electronics and vehicles.
