On what website or device are you getting this message?
Ok, then you will need to check your payment settings on the Amazon website.
To do this, go to www.amazon.ca and then
Let me know if that works for you?
Hi Sharon,Sorry for the delay.
I have been looking into this problem for you.
Are you sure the Kindle is registered with your amazon.ca account?
What is the exact error message you are seeing on the Kindle?
Are you using the 1-Click settings? Perhaps you still have the old card set as the default. Look under "Self-Service" on the right hand side of this page for "1-Click Payment Settings" and click on that. Let me know what you find...
