I was very suprised to get an email saying that international orders wont be fulfilled at this point and all orders will be refunded. My main suprise was that it took you that long to recognize it to take this step. I was wondering if you are offering any additional compensation in addition to the refunding for your backers.
“At first, we thought that additional shipping costs would be the only added complexity when shipping Soylent internationally”
This sounds very naive to me if I look at people who are running a multi million dollar business. I have the feeling that you collected the money knowing, that you wont be able to ship the product in the time you estimated. The money you have collected helped you in paying your bills, setting up your business and collecting additional money. Now you have a finished product and are unable to deliver for reasons which might have been obvious if proper homework would have been done.
Long story short, I think your international backers have earned a compensation based on the support they have given the company.
