Nice art, for sure, but again not sending outside the US. I see you are asking for interest outside the US, but it's difficult to get a clear sample of that population either here or in UC. True there's people from Australia, UK and Asia, but the vast majority are from the US.
So it's a shame when a project says "shipping only to the US", but you probably knew that before. I can see the logic in previous projects with copyrights difficulties, but in this one, I fail to understand the reason, other than convenience, which I can't argue against besides saying that you are missing a part of this community.
Wow a mature response for once regarding this issue, respect. This is well worded and I think offers some caution on ignoring international. I think you are correct in the assumption they are doing this out of convenience and also avoiding the rage of those who will complain about international shipping costs if they do include it. As you may know, they have been very up front with some of their early projects and costs.
http://albinodragon.com/blog/dragon-crate-kickstarter-analysis/An interesting metric here is that even though international shipping only accounts for 25% of the backers, it was about 50% of the total shipping costs.
Keep this in mind when offering shipping worldwide.
Also don't forget how much more time intensive shipping international packages can be. You'll ultimately have a lot of data processing to do trying to correct international addresses as well as filling out accurate customs forms.
Based on this, I would have to believe they found it either too much of a pain or they would have to charge so much for international shipping to account for cost and time, not to mention the previous problems with fraud due to lack of ability to fully track in some countries. Either that or they would have to partially account for this in the cost of the deck itself and raise the cost for everybody. However, at the current price of $15/deck it seems they should be able to handle it. That said, not sure who will buy many if at all at that price.
My impression and assumption is that international buyers have increased lately and they may end up with more than 25% which Don also seems to agree with, especially in AP. It should be possible to also lower the price of the deck overall to increase the appeal, but then also charge appropriately for international shipping without the cost being too high for you all. jsantafe has a good point here. From my perspective the price HAS to come done to a reasonable one considering what this deck is (not licensed and not embellished with embossing, foil, inner printing, etc), but you should also consider including international to make it a success, even if that means charging a little more for shipping to those that want it and dealing with the 'not fair' crowd.
