You really wonder is Amazon keeping USPS financially viable because they're now paying USPS to operate their postal trucks for delivery even on Sundays? In fact, Amazon's logistics are so demanding that they're probably keeping railroad trailer on flat car (TOFC) and doublestack container railroad operations "in the black," and Amazon is now buying its own fleet of cargo get transports because they can't rely on the FedEx and UPS air cargo fleets.

I'm a casual fan of large scale logistics. For example, I love reading about the build-up to D-Day in WW2 and how Apple has perfected their logistics to a point where they have virtually zero inventory despite having a supply chain that stretches around the globe. Or how Wal-Mart expanded like they did during the 1980s and 1990s.

But I don't think anybody has done anything on the scale of Amazon with regard to moving product from one place to another. And I remember when they were just a bookseller on the Internet with maybe just a couple thousand titles. People laughed at that business model for years.
