Manage Your Fire & Kindle Payment Settings

1. Manage your content and Devices.
2. From Settings, select Edit Payment Method below Digital Payment Settings.
3. Select the desired credit card information, or add a new card, and then click Continue.
4. Enter the desired billing address, and then click Continue. You will be taken back to theDigital Payment Settings page where you can view your edited 1-Click payment method.

Follow the link below labeled "Help Search Results". It will take you to Amazons help site and give you the same instructions as above but will ask you to log into your account so you can actually do the above process without have to search around for the correct links.
