The U.S. Postal Service is virtually bankrupt. There's been talk of having deliveries eliminated on Saturdays. Most residential deliveries could be cut to Mondays, Wednesdays and Fridays. Most businesses aren't open on Saturday and those that are frequently have their business office closed. They could certainly do without Saturday delivery.
I recently kept a two-week log of the mail I received. I got 39 solicitations from political candidates, travel agencies, medications, magazines, charitable organizations, etc. I got 10 business letters and seven magazines, five of which I didn't order. The business letters were notifications from insurance companies, reminders to send in income tax, bills from credit card companies, etc. None of this required action in less than a week. This is why three days a week of residential delivery would be adequate. Many businesses could function efficiently with fewer than five deliveries a week. This is only one way for the postal service to save money.
