buying Whole Foods and slashing prices on organic produce and pasta sauce, among other items, is reportedly bringing increased foot traffic to the grocery chain.
Across the U.S., Whole Foods stores saw a spike of more than 25 percent in foot traffic on Aug. 28 and 29, the first Monday and Tuesday that the merger was complete and as discounts were starting to roll out, location intelligence company Foursquare told CNBC.

According to One Click Retail, an e-commerce firm that has been tracking Amazon sales, the internet giant had more than 2,000 Whole Foods items on its website in the first week that it bought the grocery chain.
Through Amazon's Fresh, Prime Now and Prime Pantry platforms, the company saw $500,000 in sales on Whole Foods items in "week one," One Click Retail found. Top sellers were coconut water, deli turkey breast and frozen fruits and vegetables, the firm added, based on its analysis.
