For a multiple product order, we will make every attempt to ship all products contained in the order at the same time. Products that are unavailable at the time of shipping will be removed from the order. You will only be charged for products contained in a given shipment, plus any applicable shipping charges. You will only be charged for shipping at the rate quoted to you on your purchase receipt, unless we contact you and get authorization for additional shipping charges. This sometimes happens especially with large over-sized shipments such as body panels, hoods, etc.
