I think they are doing shipping in a way to cover themselves and make sure that everybody pays exactly what it costs. They are also offering $10 credit towards the shipping which is nice (and means their estimates are likely pretty close). I am sure that we will see updates regarding what they expect it to cost. It's a little frustrating as I'd rather pay everything up front but it's not a huge issue. The lack of EU shipping is much more of a concern to me personally although they are looking into this. Could you give some more information on this please:
As this has recently happened in another kickstarter that has received close to 6 months delay.
Specifically the change in the shipping costs (what they were estimated to be, what they ended up being).
