When you subscribe you’ll enter a debit/credit card that will automatically be billed monthly for monthly memberships, or annually for annual memberships. Your card will be automatically billed around the same day every month/year as the day you joined. If the card on your account expires, or a billing transaction fails for whatever reason, you’ll receive an email asking you to update your payment information. You can do this just by going to your “My Home Page”, where you can update any of your account information, including the debit/credit card to bill your membership to.
