Lear,
did you read my other post about getting an online US DEBIT card?

That's not the same as using a US CREDIT card which might be hard to get by, rather setting up another online means of payment that you can fill via paypal or others and that adds something like 20 $ cost to what you already paid for your Kindle.
Best regards,
Andy
