Your statistica link is misleading. https://www.thebalance.com/largest-us-based-grocery-chains-3862932 https://www.thebalance.com/largest-us-based-grocery-chains-3... The main problem is that Walmart is not and never was a grocer - it is a retail store that subsidizes its grocery with its retail success. Nor is Amazon a grocer. Buying Whole foods will not make Amazon a successful grocer. My s/o asked "But Whole Foods will turn over all their knowledge to Amazon with the takeover, of course?" to which I replied "Once Mackey leaves, Amazon officers will be given a 4-inch binder by departing Whole Foods staff with 700 white blank pages and a top page that says in big letters "F* You!". Grocers have existed for 100s of years in a very competitive market. Despite all the bravado and technology, neither Walmart nor Amazon know what a quagmire they are getting into by wading into that tar pit. Whole Foods is a poison pill that marks the beginning of the end for Amazon's growth.
