Sometimes products become out of stock before the system has a chance to update inventory. We will notify you by email that it is unavailable with an estimate of availability. We will ship your product as it becomes available or you can cancel that part of your order. Usually, products ship 1-3 business days. However, there may be times when the product you have ordered is out-of-stock, which will delay fulfilling your order. We will keep you informed of any products that you have ordered that are out-of-stock and unavailable for immediate shipment. You may cancel your order at any time prior to shipping.
