With Amazon's introduction of cashier-less shopping at Whole Foods accelerating the Retail Ice Age for competitors failing to invest sufficient CapX in artificial intelligence, Amazon stock is Burt Flickinger's "Mornings with Maria" Retail Roundup "Flick's Picks" of the week. With consumers still skittish about in-store shopping, Amazon's innovation reduces the average Whole Foods shopping trip to 10-12 minutes from 40-60. Amazon's savings from rooftop solar meanwhile is simultaneously decreasing prices while increasing customer counts. Maria and Burt also discussed consumer spending trends, the looming massive holiday season out-of-stocks, and the implications of Dollar General's plans to open 1,000 new stores.
