POD Bits

These products are printed on demand by third-party suppliers, and shipped directly to you.  The print-on-demand supply model makes sense to me, because there's no inventory and less waste using this manufacturing system.  If no one wants to purchase the product right now, no materials, labor, or energy are wasted in producing it, no space is wasted in warehousing it, and no dollars are wasted doing all of those things.  This creates a vibrant marketplace with many designs to choose from, with less environmental impact overall.
