The problem with this anecdote, and many of the comments I see about "Amazon delivery" is it only manages to address Amazon as a last-mile carrier. If you look at the "Ground Control" infographic in the article, a significant portion of logistics is in the linehaul network: tractors + 53' trailers full of thousands of packages. At the end of the day you don't really know if Amazon, Fedex, or USPS handled these shipments, all you see is the guy who shows up to your door. I imagine there is the potential for huge savings to have Amazon vertically integrate this. Sure, personalized delivery to your doorstep is a tough problem to solve. But delivery of thousands of packages between point A and B? Not as tough.
