When Amazon’s $13.7 billion acquisition of Whole Foods becomes final on August 28, 2017, shoppers will immediately see deep discounts on a plethora of items, including salmon, avocados, baby kale, and almond butter – all products that are normally rather pricey, regardless of where you shop. 
The following week, look for dropping prices on bananas, eggs, ground beef, rotisserie chicken, butter, and apples.
In a joint statement released August 25, 2017, Amazon and Whole Foods said:
“The two companies will together pursue the vision of making Whole Foods Market’s high-quality, natural and organic food affordable for everyone. Whole Foods Market will offer lower prices starting Monday on a selection of best-selling grocery staples across its stores, with more to come.”
One strategy consultant who previously worked for Amazon in its grocery business expects Whole Foods prices to drop 15-25% in some categories. 
Amazon said customers will continue to see prices slide at Whole Foods stores, and Amazon Prime members will eventually see some special discounts not available to other buyers. Analysts say about 70% of Whole Foods shoppers are also Amazon Prime members.
