I combine shipping on multiple orders . I can't do anything about sticky-fingered opportunists who spirit away packages, never to be seen again, however. We'll find a way to get it there. Dog sled, Pony Express, camel train, carrier pigeon, dolphin, army ants, tortoise-back. Unfortunately, I have to declare the contents for customs, and this makes the package a higher-risk target.
Airmail is about twice as much, but much zippier.
