We are unable to add rush production after you approve your proofs. After all proofs for an order are approved, we automatically add your order to our production queue and begin printing it. This queue is optimized to process hundreds of orders quickly and without delays.
Finding and moving your order ahead in the queue is disruptive and unfair to other customers. Since rushing after approval delays the shipment of orders that were already placed we aren't able to do it.
If you need your order fast, we recommend always choosing rush production during checkout.
