In 2017, Amazon made its biggest purchase to date when it bought Whole Foods for $13.7 billion ($17.6bn/£14bn today), with the aim of selling fresh produce at cheaper prices. The e-commerce giant pushed ahead with changes to the retailer, bringing down the price of some products and introducing the Amazon Echo to shelves.

However, the move came with criticism that Whole Foods had sold out to "one of the most disliked companies in retail".
