(AP) – The U.S. Postal Service hopes to save $3 billion a year through a series of changes reflecting greater reliance on streamlined regional networks. The proposal, announced Thursday, would adjust mail delivery times while maintaining a commitment to a maximum five-day delivery for the flagship Ground Advantage program and a maximum three-day delivery for local first-class mail. The details were unveiled Thursday by the Postal Service ahead of a Sept. 5 meeting in which the proposed changes will be discussed before being submitted to the Postal Regulatory Commission. Election mail won’t be affected because the proposed changes would begin next year. (Photo: AP)
