Anyone else have (and still having) issues with the USPO?  In my case, I have 5 check written to me from clients as far back as March 2021 yet to arrive at my office.  I had a tax return envelope that I mailed to a client 5 miles away and it took a month to arrive; 2 others within 20 miles that took over 20 days.  I've had envelopes mailed to the correct address with correct postage marked RTS, uncancelled, and the client has lived there for years.  I have contacted both MO senators, only Sen. Blunt has given me any attention so far.  What do we do?  These are time-sensitive documents that have penalty and interest implications at stake.  I have never had this problem in 45 years in the biz.  Am I alone?  Is this the year to retire?  Or was that last year?
