Not quite everything, I shop at American Apparel because their merchandise is well-made and made in America. Also most cars you buy here are made (assembled) here (or at least in North America), because it's cheaper than shipping manufactured cars (though the parts are still produced overseas).
I'm also surprised Kroger is #2, I would have guessed Costco, Home Depot, Target, and even Walgreens/CVS would be ahead of them; but at guess that's at least partly because I've never lived in a state with a Kroger.
Looking at average transaction price would also be an interesting column to add to this, but that's probably more detailed information than the companies publicly release. That data would see Apple and probably Costco go up on the list (as well as Macy's and Amazon probably).
