The shipping costs look kind of confusing.
We structured it so that $10 is always included for shipping as a base cost (for domestic shippers).
If you are international you will add $20 to the base to make a total of $30 to cover the shipping to you.
So to be clear if you are INTERNATIONAL you will ONLY pay $30 for shipping - flat.
If you are domestic you will only pay $10.
It looks kind of wonky because of the way we structured it to include shipping costs for both domestic and international. Kickstarter only lets you check a box that says "Add International" and then specify a flat price for the whole world.
