Custom Boxes While You Wait

A store in a strip mall with a computer aided machine to custom cut boxes to order. You bring in what you want to ship, it gets 3D scanned, and then your box options appear. You'd have stacks of sheets of cardboard in various weights/colors, and the machine would know how to scale basic designs to suit. There'd be a piece price and a sheet price, depending on if you want one or as many of your design as can be cut from the sheet.

An ink-jet could custom print the boxes to order, as well.
