If the U.S. Postal Service has its way, the mailman could soon double as the grocery delivery man.

The organization is seeking Congressional approval to expand its grocery-delivery test program with AmazonFresh. Amazon is looking to expand its delivery service — and USPS leaders want their employees to carry the weight.

As part of the test program, USPS employees deliver groceries for AmazonFresh in San Francisco during early morning hours when its delivery vehicles would normally be parked. The extra-curricular work is one way the organization is dealing with financial straits, including a $1.96 billion loss last quarter, as a result of declining snail mail shipments.

The sheer size of the USPS makes it an impressive service apparatus. Its legions of workers total nearly 500,000, covering 227,000 routes and operating a fleet of 212,000 vehicles nationwide, according to Vox. And change doesn’t come easy — or cheap.

The organization has had to invest in new technologies to make the switch from delivering letters to groceries. USPS employees, clad in reflective uniforms for safety, use iPhones to scan and track AmazonFresh shipments. The organization wants to spend $10 billion to upgrade its fleet and sorting equipment by 2018. (via The Wall Street Journal)
