DM NEWS reports that First Class volume will "decline 2.8 percent from a 2006 estimate of 97.546 billion pieces to 94.775 billion in 2007. That decline of 2.771 billion pieces would cost the USPS $1 billion in revenue. The USPS also projects a 1.9 percent rise in Standard Mail volume, from an estimated 102.763 billion in 2006 to 104.721 billion in 2007. That amounts to a revenue increase of $400 million. And, according to the projection, Standard would expand its volume edge over First Class to almost 10 billion pieces." See the full article.
