If your original order was for 299 or less units AND you ordered the glossy finish on your disc, you will not be able to increase your reorder size.
Orders that are for 300+ units are silk screened. (It would be very expensive to manufacture the glossy on disc print in large quantities!)
You would need to contact us for assistance in updating your reorder quote so that we can change the on disc print and the quantity for you from the back end or you can create and save a new quote.
You'll also want to keep in mind that order quantities at 300+ are replicated and 299 units and under are duplicated.
