You can change the payment method listed on your account, or add another payment method, in the Payment Methods section of your account page. The link to access the Payment Methods section is located in the My Account menu on the left-hand side of your browser window when you are on your account page. You can add a new payment method by clicking on the Add new button, or delete an old or invalid payment method by clicking on the Drop button next to where the payment method is listed. Also, the last payment method you enter in the Payment Methods section of your account will be flagged as the preferred method on your account. Remember, if you are a Monthly Platinum Club member and have to delete the credit card listed for your renewal from the Payment Methods section of your account, you will need to update the Platinum Club Preferences section of your account as well.
