We subsidized all shipping options by the same amount when creating the Kickstarter campaign. This allowed us to offer free shipping in the U.S. (for two pledge tiers) but each international option already has that original discount built into it as well.
There are many reasons your specific location may have a higher shipping estimate. The three majors reasons are this: these are conservative estimates, customs-friendly shipping is more expensive, and we are using a U.S. based fulfillment service.
We decided to provide equal subsidy for all options and not charge shipping until the pledge manager. At the cost of not having the extra bump of shipping money in the funding goal metrics, it gives us the ability to reduce shipping costs for international backers based on the overall success of the campaign.
Don't risk missing out on the game by cancelling your pledge early! If you are not satisfied with the final shipping rate to your country, we will issue you a refund for your pledge. So there is no risk for waiting until then to see the final numbers.
We encourage you to reach out directly if you have any other questions or concerns about international shipping rates.
