Amazon Prime benefits roll out to all Whole Foods stores

``Beginning Wednesday, members of the $119 yearly service can earn additional savings on select items at all of Whole Foods' 466 US stores. Whole Foods introduced the discount program in May and has been slowly adding states before going nationwide... The discount program is part of Amazon's increasing influence on the grocery chain, which it bought for $13.7 billion last year. The companies are also expanding delivery at US stores.''
