Amazon Payments International Support
Amazon Payments accepts credit card payments from users worldwide. In many cases you can use your existing Amazon account.
However, Amazon Payments does not currently support International Amazon Accounts that have been used with Mechanical Turk.
If your International Amazon Account has been used in the past with Mechanical Turk, you will be asked to complete a signup form when using Amazon Payments that requires a US address.
In order to avoid this, you will need to create a new Amazon Payments account at purchase time. Instructions for creating a new account are below.
