The Postal Service has more than 10,000 prices contained in a 1,800-page customer manual known as the Domestic Mail Manual (DMM). The DMM provides individual and commercial mailers with information about postal services and standards for both domestic and international mailings. The Price List, also known as Notice 123, contains domestic and international retail and commercial prices for all postal products and services.
No pain no gain. The U.S. Postal Service has reduced spending over the past decade but it has come with a downside, notably a reduction in service. Over the past decade the Postal Service has reduced labor costs by $10 billion, improved productivity, and generally reined in spending.
