I recommend that the Post Office deliver to your home only three times a week. Some will be on Monday, Wednesday and Friday and others on Tuesday, Thursday and Saturday.
There is little postage that is so time sensitive that a day’s delay will make any difference. The internet and e-mail has monopolized that instant communication. Postal delivery will never be able to compete with that.
For those that must have next day delivery there is Fedex and next day services. If you require daily delivery you get a box at a postal station. Many businesses already do that.
This would cut the fleet in half, one of the largest expenses of the Post Office.
Currently you pay to have a box at a postal station, yet they deliver to your house for free. When you think about it, this makes no sense.
Daily delivery should go the way of the pony express.
