The tech giant bought the grocery chain for almost $14 billion and announced last week it would immediately lower prices.
"This is just the beginning – we will make Amazon Prime the customer rewards program at Whole Foods Market and continuously lower prices as we invent together," Amazon Worldwide Consumer CEO Jeff Wilke said.
“There is significant work and opportunity ahead, and we’re thrilled to get started,” Wilke said.
Amazon slashed prices on a range of Whole Foods organic items, including apples, bananas, avocados, large brown eggs, rotisserie chicken and salmon.
The tech giant and retail chain technology teams are also beginning the process of integrating Amazon Prime into the Whole Foods Market point-of-sale system.
