To keep costs down for everyone, we've limited this Kickstarter campaign to four levels. One of those levels includes EU/Canada/Australia-friendly shipping, and another is for pickup in Germany at Essen Spiel; since those add-ons originate in the US, we'd have to ship them to the other countries before they were sent to you, which causes all sorts of logistics issues and expenses. Because less than 5% of our backers get add-ons, it would introduce a huge amount of complexity into the process that would only benefit a few folks.
The good news is that if you really want just one or two of the items that are available at the $100 and $300 tiers is that we'll have any leftovers available on our website at some point in the future, so you'll be able to pick them up that way. While that's not great for international backers, who have to pay shipping, you'd have to pay the extra shipping for them from the US anyway.
