Nice try, delivery guys. One month after the financially beleaguered U.S. Postal Service announced it would end Saturday delivery in an attempt to save $2 billion annually, Congress passed legislation Thursday requiring six-day delivery. The law does, however, leave room for the Postal Service to alter what services it offers on Saturdays. While it will no longer pick up or deliver first-class mail, magazines, and direct mail on Saturdays, the USPS will continue to deliver packages and pharmaceutical drugs. The Postal Service has said it could need a taxpayer bailout of more than $47 billion by 2017 if Congress does not allow it flexibility in changing its business model.
