Holiday Mail Deadline

The U.S. Postal Service says about 7,000 post
offices will be open for extended hours during the holiday season.
It expects nearly a billion cards, letters and packages to be
mailed December 17th, the busiest day of the season. That includes
275 million cards and letters. The average daily volume for cards
and letters is 82 million.
The Postal Service is also encouraging people to avoid lines by
using automated postal centers, which are open 24 hours a day.
In November it issued a deadline of December 15th for packages
sent using the least expensive option, parcel post, to arrive by
Christmas. For parcels sent first class or priority mail, the
deadline is December 20th. Customers have until December 22nd to
send Christmas packages by express mail.
