Trump Targets Amazon in Call for Postal Service to Hike Prices by Reuters U.S. President Donald Trump on Friday targeted online retailer Amazon in a call for the country's postal service to raise prices of shipments in order to recoup costs. "Why is the United States Post Office, which is losing many billions of dollars a year, while charging Amazon and others so little to deliver their packages, making Amazon richer and the Post Office dumber and poorer? Should be charging MUCH MORE!" Trump wrote in a post on Twitter.
