If you decide to activate a Subscription Service, you authorize us to periodically charge, on a going-forward basis and until cancellation of either the recurring payments or your account, all accrued sums on or before the payment due date for the accrued sums. The subscription will continue unless and until you cancel your subscription, or we terminate it. You must cancel your Subscription Service before it renews in order to avoid billing of the next periodic subscription fee to your account. We will bill the periodic subscription fee to the payment method you provide to us during registration (or to a different payment method if you change your payment information).
