It’s been a year since Amazon bought Whole Foods, and thought the organic supermarket chain isn’t all that different, the partnership has prompted changes to others players in the grocery business.

Competitors such as Kroger, Costco, Walmart and Target have all taken measures both online and in their brick-and-mortar stores to prevent losing customers by keeping prices low, expanding online and in-store pickup options and making technological changes. One growing trend is the “click-and-collect” option, a hybrid e-commerce model where people can buy groceries online and then pick them up in a brick-and-mortar location, at their convenience.
