This does not apply to everyone, but if we did not quote shipping, or this is a large quantity order, please continue. At the time your order is placed, it may not include shipping costs or any overrun amounts. We do not know if an overrun or an underrun of your product will occur. On most production runs, this usually is plus or minus 5-10%. Until the order is ready to ship, we do not know the exact number of boxes. The shipping (and the over or underrun, if applicable) amount is charged to your credit card when the product has been shipped. Orders will not be shipped until these charges have been paid. You will only pay for the quantity of product that is actually shipped.
