Yes you can. Amazon Payments does only accept Credit Cards. We figured out two ways for you to get it done without having one. Simple, isn't it?
1) Ask a friend to do it with his Credit Card for you.
2) Send the money you want to pledge to our account in U.K. or in Germany. This is a Neteller-Account that allows us to generate a Virtual One-Time-To-Use credit card number, working with Amazon Payments without a problem. We guarantee to pay back the amount if the project doesn't reach it's funding goal. Details how to do this are in the Update No 2. - and you just need to contact our German Coproducer firstname.lastname@example.org - responsible for the financial part of this project. He will send you every detail as well.
