If an item is out of stock on the day your order is placed, you will receive an email letting you know that the order could not be placed. We will continue trying to place your order every day. After 15 days, if the product is still unavailable, you will receive another email to let you know. If the item is still out of stock after 30 days, we email to let you know that your order was cancelled, but your subscription will remain active and we will place your next order on schedule. If you have any questions about your subscription orders, please contact Customer Care.
