If a Subscription product is temporarily out of stock, you will receive email notifications on days 1, 15, and 30. If the subscription order has a frequency of fewer than 30 days, the order will be canceled before the next scheduled subscription order date. The out of stock subscription product will ship when the item is back in stock, or if you have a frequency of fewer than 30 days the product will be shipped on its next order cycle. You will continue to receive Subscription shipments for other products you have set up, if any. If the remaining in stock Subscription(s) fall below $40, net of tax and discounts, you will be charged $7 for shipping or you can add other items to the order until it is above $40 in order to receive free shipping.
