It makes sense to me, but I will have to speculate a bit here.

The amount of increase in demand for food delivery from both restaurants and grocery stores has climbed significantly in the last couple of years.

Look at companies like Post Mates, Yelp’s eat24, supermarkets offering deliveries, and prepared meals such as MagicKitchen.com.

Amazon has their own service for getting restaurant food to you, and they probably see an area of opportunity to have a company like Whole Foods, who gets local ingredients and products into their stores, to later deliver those products much more easily to consumers. It seems like a smart move and a big opportunity to take its infrastructure improvements that it’s made in e-commerce and bring those to supermarkets.
