President Barack Obama watches Amazon worker Eric Phillips pack a box during a tour of an Amazon fulfillment center on July 30, 2013 in Chattanooga, Tenn. - 

This final note on the way out, in which Amazon wraps up the free-publicity trifecta it's been enjoying the past day or two, thanks to the White House.

Yesterday, ahead of the president's speech, it was the 7,000 new jobs Amazon's adding. Today, it was the speech, of course.

Tomorrow: A brand new Amazon Kindle Singles e-book featuring an interview with the aforementioned President of the United States. Mr. Obama's sitting down for an interview with the editor of Amazon Singles. It'll be available in the morning.

Free, I should add.
