We priced the cost of sending decks to places all of the world and the costs ranged from $10 (Canada) - $30 (Australia). Everywhere else was in-between. This would all be much easier if Kickstarter allowed us to price shipping individually or if USPS First Class didn't have a bad reputation for timely delivery internationally.But here's our plan since these are the meat-space conundrums we work within.
For anyone shipping internationally whose actual shipping cost is under $30, we will send you the difference in decks. So if you buy 1 deck for $10 + $30 in shipping and are in Canada, and it costs $10 to ship to your address. That means you paid $40 but it only cost us $20 ($10 to print the deck and $10 to ship it), so we will send you 2 decks, that's $20-worth.
We asked some of our international Backers and they said it seemed a fair solution to the difference between estimated and actual shipping costs; we hope you agree. Feel free to message us with any questions.
