The U.S. Postal Service is not waiting any longer for permission from Congress to quit delivering mail on Saturday’s. It says it’s going ahead with plans to start five day-a-week delivery in August. Postmaster General Patrick Donahoe says the agencies financial condition is urgent, and the change will save about 2-billion dollars a year. Under the plan, letters would be delivered to homes and businesses only from Monday through Friday. Packages would continue to be delivered on Saturday’s. Mail would still be delivered to post office boxes on Saturdays and post offices now open on Saturday’s would remain open. The Postal Service has been advocating a shift to five-day delivery for several years, but Congress has not approved it.
