I do online sales and rely on the USPS but Wednesday has been declared a National Day of Mourning -
“announced by President Donald Trump on Saturday, will honor the 94-year-old former president who died Friday night. The federal government will be closed on Wednesday, as will the New York Stock Exchange and Nasdaq. A state funeral will be held at the Washington National Cathedral that day, beginning at 11 a.m.”
This was also done for former presidents Ford and beloved Ronald Reagan.
The Post Office was not shut down for Reagan! This is nuts. WHY?
