International shipping is a difficult one for Kickstarter projects. It takes time and effort to learn international logistics at a time when there is so much else to do. And in small quantities it is very expensive which can be off-putting for backers.
Today, due to popular demand, we are adding international shipping for Canada, the UK, and Australia. The shipping costs include the price for shipping itself, tax and duty. Because this is already so high we aren't including any extra for packaging and labor, it's just a straight shipping cost.
If our project takes off and we see pledges rolling in from around the world we will be able to dedicate more time and effort to international logistics. We hope to reduce the cost of shipping, but while are quantities are low we are unfortunately paying consumer rates.
