Hugh Pickens writes writes "The Postal Service has been losing billions of dollars each year as Americans increasingly rely on online communications that drive down mail volumes. Now Reuters reports that the Postal Service plans to drop Saturday delivery of first-class mail by August saving $2 Billion per year. "The Postal Service is advancing an important new approach to delivery that reflects the strong growth of our package business and responds to the financial realities resulting from America's changing mailing habits," says Postmaster General Patrick Donahoe. But thePostal Service is already facing some pushback for moving forward with delivery schedule changes."Today's announcement by Postmaster General Donahoe to eliminate six-day delivery is yet another death knell for the quality service provided by the U.S. Postal Service," says Jeanette Dwyer, president of the National Rural Letter Carriers' Association. "To erode this service will undermine the Postal Service's core mission and is completely unacceptable."Package deliveries will continue under the new plan and were a bright spot in a bleak 2012 fiscal year, with package revenue rising 8.7 percent during the year. Donahoe saysthe changes would allow the Postal Service to continue benefiting from rising package deliveries as Americans order more products from sites such as eBay Inc and Amazon.com Inc."
