You can easily add a credit card to your account for automatic billing of subscription fees, redeemed gift codes, and redeemed discount codes.

First, go to the account dashboard or "management portal". From here you'll want to scroll to the very bottom until you see "Account Configuration".

Next, click on "Account Payments and Disbursements".

Once you've clicked into the Account Payments and Disbursements screen, you'll want to click "Set up a payment method".

From this screen, you can enter your credit card for automatic payments associated with subscription fees, redeemed gift codes, and redeemed discount codes.

That's it! Once you click "Save payment method" your card will be saved on file for all future payment needs.
