So, Double Fine's Kickstarter effort is about to come to a spectacular end.
While they clearly do not need my help, I have been trying to fund the project. Kickstarter uses Amazon Payments to process transactions, and the final step of checkout shoots you over to their site: http://cl.ly/0z38150n1w2l021X2U3m
However, having logged into my amazon.com account, I get redirected to a page reading: "This functionality has been disabled for your account. Please contact-us to know more."
If I try to create a new amazon.com user at https://payments.amazon.com, the 'Country' field is locked to 'United States' and can't be edited. It may be relevant that my Amazon account has my country as Australian, seeing as that's where I live.
Why will they not take my money?
