> Logistically, something like that could save the post office a bunch of money Debatable for lack of data. Remember, the post office doesn't do special delivery runs just for you, rather to make deliveries to everyone on a route. If your neighbors are still asking for their mail, then the post office still has to pay for labor + gas + vehicle maintenance to make the deliveries, they just skip your house. What you'd actually have to do is JIT dynamically figure out the daily delivery route, and see if doing so would allow the post office to employ fewer delivery people to cover a smaller number of overall daily deliveries. Of course, theoretically speaking that's relatively simple - but in the real world, different localities will derive different levels of benefit (including possibly zero) and it's a very expensive system to build to find out how much benefit would be derived.
