Over and under runs are common in custom printed packaging production and refer to the final quantity of the product being either more or less than the original order quantity. This is detailed in our proposals as a plus or minus percentage, and you will be billed pro-rated for the actual shipped amounts. Over and under runs happen due to various factors such as the amount of material allocated to each job and the efficiency of the set-up process. However, semi-custom packaging orders are usually produced in exact or very close quantities to the original request. Rest assured that you will only be billed for what we make and ship, whether it’s more or less than your original order quantity.
