What is the 3% under allowance policy and how does it affect the final invoice quantity?

Our 3% under policy is to insure the right amount of shirts will be printed. As screen printing is an art and not an exact science, oftentimes there are small errors on press, from the shirt vendor or random acts of God, However, we will always refund your card if we do not meet the required amount up to 3% under the quantity Order. If the damaged amount is greater than 3% we will reprint the goods.
