 *	If a subscription has a free trial and no signup-fee, automatic renewal is not possible for the first payment because the initial order total will be 0, after the free trial the subscription will be put on-hold. The customer will have to login to his account to renew his subscription. If a Mastercard or Visa card is used to renew the subscription subsequent renewals will be automatic throughout the duration of the subscription, if a Verve card is used automatic renewal isn't possible.
