"Unless you have received Premium Membership through an offer that is not subject to auto-renewal, your Premium Membership is set to automatically renew each year. You authorize UPS to charge your default payment method for the current and subsequent subscription costs as described in the UPS My Choice Service Terms. You can cancel automatic renewal at any time by managing your membership information."
