Yes, Sightbox members can change their billing date during the course of their 12-month membership as long as the new billing date stays within the same calendar month.
Your payments are monthly installments towards your membership’s total cost and you are not able to "skip" a month’s payment. In the event you are unable to complete your payment for a month, Sightbox can postpone the payment (with no additional late fee) for that individual month into the following month’s scheduled payment. This means that both months’ payments would be processed at the same time. Please note, billing postponements for more than one month are unavailable at this time and cannot be granted.
To request a billing adjustment, please email customer support at email@example.com.
