The USPS wants to go to a 5-day delivery week. Sounds like a fast way to hammer the business prospects of companies that depend on postal service AND a nightmare for people who pay their bills or send vital documents via snail mail.
This idea gets a thumbs down from me. A stamp is a promise to deliver (Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.)
So, USPS, try dumping all the non-packaging merchandise you carry (tote bags with stamp pictures, greeting cards, stuffed animals, anything that isn't directly related to mailing something). Some of the items for sale in my local post office are from the old 37-cent stamp days. Stick to what you know--dependable delivery.
