When placing your orders, we would like a purchase number from you. This gives you easy reference to check the order acknowledgement that you will receive in a few days after placing your order. Please check this acknowledgement over carefully to assure that the truss order has been correctly recorded. There will be a ship date on the acknowledgement. This means the shipment will be on or before the date specified. If delivery must be on a certain day, a "Must Have: date will be given".
