International shipping is calculated at a rate based on our experience shipping other premium, hardcover books overseas. The cost varies by country, and is reflected in the shipping prices which appear when you make a pledge. A great way to offset the unavoidably high shipping costs is to purchase multiple copies and come to an arrangement with friends or family to split the cost.
Also, don't forget that in order to make books more available to our international backers, we are charging the same amount of shipping for up to six books per customer as we would for one book.
There is also a community-driven initiative to coordinate combined shipping, here: https://www.reddit.com/r/ForgottenWeapons/comments/bjixnc/coordinating_international_orders_for_ians_book/
