Using USPS anymore is becoming a joke.
I received a letter postmarked November 30th and I received it December 11th.
I shipped some priority mail packages with tracking which should have arrived yesterday and still nothing, tracking info says they are still moving in the system and that mail is delayed due to COVID and lack of workers.
I have friends who have mailed rent checks and utility bills locally and their envelopes never made it to their destination. They are hesitant to pay bills online. They prefer the “old” way.
Everybody’s mileage varies. I’m in a fairly high volume mail house. In or out probably half a dozen things a day, not counting junk. More in the holiday season. I get maybe one or two problem items a year. And “problem” for me is generally no more that 2 days late.
