Make sure you choose the proper plan and cancel in time.

There are three types of plans:
Annual plan, prepaid - This is paid once and is an annual commitment because it is a discounted price.
Annual plan, paid monthly - This is an annual commitment because it is a discounted price.
Month-to-month plan - This can be canceled at any time without penalty, but is more expensive.
