The new perks are expected to bring the might of Amazon's membership program to the grocery industry. Prime members shopping at Whole Foods locations simply open the grocery chain's mobile app, sign in with their Amazon account and scan the Prime barcode at checkout.
The expansion means the discounts, which include an additional 10 percent off various sale items, will be available to nearly half the country.
"Based on the positive customer feedback and successes we've seen over the past month, we're accelerating our timeline to expand these savings to all of our U.S. stores," A.C. Gallo, chief operating officer at Whole Foods, said in a statement.
The benefits roll out for the first time June 13 in: Alabama, Arizona, Georgia, Hawaii, Mississippi, North Carolina, Oregon, South Carolina, Tennessee and Washington. Amazon is also expanding benefits to parts of California and Nevada.
Prime discounts at Whole Foods stores already applied in 13 states.
Amazon completed its purchase of the grocery store chain in August and has utilized the storefronts as a means to enter brick-and-mortar retail.
The e-commerce giant in April raised the price of its annual Prime membership — which grants faster shipping and access to online streaming services — to $119, in the first price hike since 2014.
