Merger done: Whole Foods cuts prices, debuts 'farm fresh' Amazon Echo assistance

NEW YORK – A half-gallon of milk was 50 cents cheaper at a Whole Foods in New York. Ground beef was down by $2 a pound. Amazon kicked off its first day as the owner of Whole Foods by slashing prices, adding its logo on signs and setting up a stand of "farm fresh" Amazon Echo voice-assistant devices by store entrances. It's just the first taste of the moves the e-commerce giant will make at the organic grocer after it completed the $13.7 billion deal on Monday. More changes are coming: The company aims to make Amazon Prime the rewards program at Whole Foods and some Whole Foods products will show up on Amazon's site.
