As much as we would love to be able to support our international backers the way they have all supported us on all of our projects, we do not have the licensing approval to distribute worldwide yet. As a result, we can only offer this pre-order for those in the United States.
If you would like to add a deck to your current pledge level, just increase your pledge by $15 for each deck (maximum of six). You can change your pledge amount by clicking on the blue button in the upper-right that says “Manage Pledge”. You can also just add the additional funds in during your initial pledge.
