Not much of an opinion on this, but a step beyond this seems like it could be interesting. 1) You register all the products you reorder with any frequency (detergents, napkins, whatever) 2) Each package comes with a remotely readable electronic tag 3) A device periodically scans for inventory (I'm assuming very little intelligence in the tags, so an evented system is out) 4) When the number of packages per type reaches some critical threshold, you receive an email/app alert asking if you'd like to reorder Some refrigerators have this, but it would be much more interesting to have it be all products. One of the first steps would be to have some kind of open standard for the tags so any manufacturer could include them.
