[Amazon plans to invest $4 billion to expand its delivery network in small towns in the United States] Amazon (AMZN.O) said it plans to invest $4 billion to expand its delivery network in small towns in the United States. The investment will expand its rural network to more than 200 delivery stations. By 2026, the company plans to triple the size of the network and will cut delivery time for rural customers in half. Udit Madan, senior vice president of Amazon's global business, said: "While many logistics providers have given up on investing in rural customers and communities, we are doing the opposite."
