Amazon gets the Postal Service to do Sunday deliveries.

And WaPo calls it "Amazon’s brilliant plan to rescue the Postal Service and disrupt the shipping industry."

Amazon could have offered to pay the Postal Service for carrying more of its packages generally, and USPS would have gotten a much-needed injection of cash....

By launching Sunday deliveries, the Postal Service has moved to where its longtime competitors aren't. Hardly anybody in any industry delivers on Sunday, with the exception of newspapers. As a business idea....

The other reason it's disruptive? This is one of the few cases we've seen of what we'll call reverse contracting — when the private sector hires a government agency to fill its need rather than the other way around. 

This might be a good place to remind you of the brilliance of the Amazon Associates Program, which lets you make a cost-free contribution to writers like me. (The "shop Amazon" link is always at the top of this blog in the banner.)
