The U.S. Postal Service announced today that it intends to end Saturday mail delivery beginning on August 1st. According to the USPS, the move would save the government’s beleaguered mail monopoly $2 billion a year. The USPS has lost over $40 billion since 2006 and it has maxed out its $15 billion line of credit with the U.S. Treasury. With mail volume in permanent decline, the USPS has no choice but to try and cut costs.
