I just happened to stumble across this months-old announcement: Whole Foods is going to be taking over K-Mart’s location just outside the Exton Square Mall. http://exton.thetowndish.com/2015/07/whole-foods-market-coming-to-former-home-of-kmart-at-exton-square-mall/
Wow, that might be one of the biggest Whole Foods in the country.
And they’ll probably do pretty well there. With the exception of the next-door Giant, there really aren’t any other supermarkets in that immediate vicinity. Wegmans is a few miles to the west, there’s a market (maybe also a Giant) north in Eagleview, and nothing for miles to the east.
