What is overrun/ underrun?
These are words used in the promotional industry. When your order is produced our large warehouses weigh out the product that is necessary for your order. Using this method, sometimes there is not an accurate amount of product produced. You are signing on your order confirmation that you agree to an overrun or underrun of up to 10%. This means that you agree that if up to 10% more are shipped, then you will pay for them, but if 10% less are shipped, you will be credited for that amount. When dealing with big machinery it is nearly impossible to get the exact quantity. Another factor with the overrun and underrun is that we always want to ship only the product that comes out perfect so the misprints never ship. Typically the overrun that is shipped is as few as +- 3%.
