You can cancel your membership at any time. To cancel is really simple and only takes a few clicks. Go to "Account" then click "Billing" and then click "Cancel" under subscription.
Step by step instructions on how to cancel can be found here and will walk you through the process with pictures.
Cancellation request MUST be submitted at least 48 hours prior to your scheduled payment date. If you do not cancel 48 hours prior to the scheduled payment date, you are not guaranteed the next payment will be prevented. It is your sole responsibility to make sure when you cancel it is prior to 48 hours of your next scheduled payment. There will be no partial (or prorated) refunds on monthly OR annual payments.
Cancellations will be effective immediately once the cancellation request has processed. You will be unable to access the material at that time. If you did not submit your cancellation request in time and the current month’s payment has already processed, we will not issue a refund for the current month or reinstate your membership until the next billing cycle.
If you cancel and then decide to join again at a later time, you will be reinstated at the current membership rate, regardless of any special offers or discounts you received in the past.
NOTE: Cancellations near major holidays are excluded from the 48-hour window. You must cancel between 3-5 days before any major US holidays. Holidays include but are not limited to Christmas Eve, Christmas, New Year's Eve, New Years Day, Thanksgiving (including the day before and weekend after), Bank Holidays, and all holidays recognized by the Government and major religious groups.
