International shipping is expensive! We aren't a huge studio with distribution centers, so even just shipping the book to Canada costs us almost $16 (But we will do it, because Dwight asked nicely.)
We have also added Australia and the European Union because backers asked for it. The book is printed in the US, so we cannot offer a EU distribution discount. We have to ship every copy individually from this side of the ocean.
Note: UK backers - We do have the ability to send a very limited number of books to the UK next summer. If you are interested in getting a physical book, please contact me directly and we will make this happen for you.
