Our guest this week is Jason Del Rey, a business reporter who covered Amazon, Walmart and the business of online retail for more than a decade at Recode and Vox Media. His new book is "Winner Sells All: Amazon, Walmart, and the Battle for our Wallets," which takes an inside look at what he calls "the defining business clash of this generation—a battle waged for our loyalty and wallets, with hundreds of billions of dollars at stake and millions of jobs on the line."
