For multiple product orders, RT Systems will make every attempt to ship all items contained in that order at the same time. Products that are unavailable at the time of shipping will be shipped as they become available at no additional charge to you for shipping, unless you inform us otherwise. You will only be charged for shipping at the rate quoted to you on your purchase receipt. The entirety of this shipping charge will be applied to the first shipment of the order.
Also, RT Systems will make every effort to ship orders together that you place separately on the same day; but depending on your timing, this may not be possible. Best is to note the existence of another order in the notes of the second order. Shipping charges on one of the orders will be credited when it can be included with another.
