Hello, I am considering an order for [quantity and printed item]. Please explain whether you propose any delivery-quantity variation, how its limits would be agreed and whether a shortfall or excess requires prior confirmation. How will the quantity be counted and recorded at delivery, and is billing based on the ordered quantity or the agreed delivered quantity? For a shortfall, explain replacement delivery and charges. For an excess, explain whether it is charged and how my agreement is obtained. This enquiry does not accept unspecified quantity differences or extra charges.
