Under the traditional month-to-month plan, you can cancel anytime (you might have to pay for the remainder of the current month).
Under the new annual plan, you get a discount for paying all at once. This payment is non-refundable, so the plan is comparable to a contract. Those who sign up for the annual plan generally do so because they still plan to be here in a year and appreciate the discount.
So, you can either have the option to cancel anytime on the month-to-month plan or get a discount on the annual plan. If you’re new to RW, don’t sign up for the annual plan yet–start with the standard month-to-month plan. If you like your experience after a month or two, consider the annual plan.
I hope this helps.
