Please note: All plans are offered on a one-year minimum commitment and are available on a monthly subscription or prepaid annual basis. The difference between the respective Annual and Monthly plans is in how payment is accepted. For Monthly subscription plans, a regular monthly charge will be made to the credit card you use to complete the purchase. For Annual subscription plans, you will be charged only once for the full, discounted amount. The discount rate for prepaid Annual subscription is 16.7%, which is equivalent to 2-free months.
