So this is being implemented already from a local fulfillment center level, sans drones. The actual mechanisms are actually super straightforward -- basically if a widget X sells Y amounts per day with Z variance in an area, get the low, low end of that to that warehouse/area so you only have to do last-mile delivery. Then do it with operations research (well, linear algebra) on scale. :)
