There may be times, particularly around holiday periods and special promotions when the product you have ordered has gone out-of-stock causing a delay in 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 for out-of-stock or back-ordered products and receive a full refund at any time prior to shipping, or, wait for the product(s) to be back in stock. In this case, you can notify us to ship all in-stock products ahead of the out-of-stock product(s). When the out-of-stock product(s) are back in stock we will ship at no additional cost to you.
