Don’t tell the lefty hipsters who waste their money at Whole Foods, but you can get kale at Kroger (or whatever Kroger is called in your part of the country — round my parts Kroger is called ‘Dillons’).
Here in Canada it’s Loblaws- mass-market chain that has lines of “Green” and “Organic” for the more gullible among their patrons. We do have a Whole Foods in Yorkvile but most hipsters still go to Loblaws.
NYC has really bad grocers like Gristedes and D’Agostino. Fairway isn’t bad, but isn’t a supermarket in a traditional sense.
