A study conducted by Senior Analyst Chuck Grom from Gordon Haskett in New York found that prices at Whole Foods haven’t changed much in the year since it was purchased, despite Amazon’s promise of lower prices.

As published in a September story by Forbes.com, in seven pricing studies of a basket of 108 items over the course of a year following the acquisition, Grom found that the basket’s aggregate price was just 0.8% below the price before the acquisition was completed. In addition, compared with Whole Foods’ first round of price cuts in the Fall of 2017, the basket price actually inched up 1.3%.
