Kickstarter doesn't allow us to delineate between countries/continents outside of the USA -- it's all lumped into International. In January, International postage rates from the USA increased sharply, and we are not in a position to subsidize those rate increases ourselves.
You can pledge to the Kickstarter via PayPal at the following link: http://eclipsephase.com/kickstarter/transhuman-levels
If you want add-ons with a PayPal pledge, please select the basic reward level and proceed to checkout -- there is an optional "Donation" section on the checkout page that you can use to add money for add-ons!
