I just switched from an annual plan to a monthly plan. How will I be billed?
Switching from one membership to another is easy. If you switch from a plan that was yearly to a different membership plan that is billed monthly, you will be issued a prorated credit for the remainder of their annual plan. The first charge for the monthly plan is drawn from that amount, and the remainder of the balance will go toward the next renewal(s) of the monthly plan.
The billing period would switch to monthly billing, with the new date being the date you switched from the annual plan to the monthly plan.
