"CAN I CHANGE THE BILLING DATE FROM THE 15TH OF THE MONTH TO A DIFFERENT DATE?"
No, The 15th of the month is the re-billing date. If you miss the billing date/ cut off date of the 15th of the month, you will not be eligible to receive the upcoming box. However, if you are billed and your card declines, a second attempt will be made within 10 days. In that time, you can add funds to your account or update the payment info on your account. If the charges are still declining, your subscription will be cancelled.
