Amazon and Whole Foods announced the news on Thursday.
"The two companies will together pursue the vision of making Whole Foods Market's high-quality, natural and organic food affordable for everyone," they said in a joint statement. "Whole Foods Market will offer lower prices starting Monday on a selection of best-selling grocery staples across its stores, with more to come."
Amazon said it will continue to lower prices at Whole Food stores and will eventually offer special discounts and in-store benefits to Amazon Prime members. (Jeff Bezos, the founder and chief executive of Amazon, owns The Washington Post.)
Other foods that will be cheaper beginning next week: Bananas, eggs, ground beef, rotisserie chicken, butter and apples.
"Everybody should be able to eat Whole Foods Market quality - we will lower prices without compromising Whole Foods Market's long-held commitment to the highest standards," Jeff Wilke, chief executive of Amazon Worldwide Consumer, said in a statement. "There is significant work and opportunity ahead, and we're thrilled to get started."
