We can only offer combined shipping when the combined mass of the orders reaches the minimum for an LTL freight shipment, and the orders contain the same size and box style. In that case, we may be able to hold all of the orders until they are fully complete so they can be stacked and packed together on a pallet(s). Boxes of different sizes/styles usually require separate shipping to prevent damage to the smaller size(s).
Combined shipping cannot be requested for any Rush priority or expedited ship method orders, as we need to ship these out as soon as they are completed and expedited freight service is not available. Holding them back to ship together via standard LTL freight poses a high risk for delaying the shipment of both orders.
Otherwise, we note that your jobs are related, but cannot guarantee combined shipping. Due to the prepress and manufacturing process, there is a possibility that they will enter production at different times or even on different production lines. If you have any questions about combining shipping on your particular order, please message our support team and we'll be happy to help!
