OK, so it’s not real estate marketing — but it is marketing.
Clever, eye-catching marketing: in this case for a potato chip that’s apparently popped or baked (like popcorn) vs. fried or however else such things are usually made.
I have no idea if the claims are valid, but you can say this for the company: they know their audience (the display was in a St. Paul deli).
P.S.: I suppose the other way to cut down on calories is to only eat a few of them — which is all you get for $1.09.
