For a multiple product order, we will make every attempt to ship all products contained in the order at the same time. Customers that place orders that contain products that are unavailable at the time of shipping will be notified via email and/ or phone of the out of stock item. Once the item is ready to ship, the customer will be notified via email and tracking information will be sent. You will only be charged for shipping at the rate quoted to you on your purchase receipt. The entirety of this shipping charge may be applied to the first product(s) shipped on a multiple shipment order.
