For the most part, shipping fees are courier fees. When I've ordered things in the past I call to make the order and request they ship regular snail mail. Deliveries are usually only a few days longer but a whole lot cheaper. Some packages have been too large for the mail (exhaust) and it had to come courier. I also lessened the charges with those by completing the customs work myself for free rather than pay them $70 to simply fill out a form.
By the way an internet search indicates you should have your mailed item 3 - 7 days after it has been sent. It's not coming over on the QM2.
