Only people on my route using checks through the mail to pay bills are age 60 and over. Checks, stamps and nicely printed return address labels all cost money. All bank websites let you pay your bills for free. It's 2026, not 1976, use your banking apps. Now checks are stolen or lost in the mail every day somewhere let alone how long snail mail takes to get it there.
And if you think the PO cares about your mail, when was the last time you saw a tv commercial that wasn't about package delivery and was about piece mail only.
USPS- We deliver letter mail. Well sometimes, usually late, usually right....maybe.
Only mail they track anymore are political mailings which are free to ship anyway. Remember when a certified was actually accountable.
