Given the multiple steps, complexity and unpredictability of vinyl production, the final delivered quantity may differ from your order quantity. For jobs below 1000 units, the over/under allowance is +/- 10%, with a shipped quantity typically being an overage of 3% to 8%. The overage allowance helps ensure we deliver at least your order quantity. If the shipped quantity is below the order quantity plus overage provision already charged, we will refund the difference to reflect the actual units shipped.
