I bought some today at a VA hospital “Canteen” store.
Old answer above…

They can be purchased from Dollar General Stores. The company that distributes them is Barbara Creations in Skokie, IL. You could ask them who they distribute to. I actually contacted them directly and if no luck at another store, I will be giving Terry a call back and driving the two hours to pick them up. Hey, they are my favorite sunglasses of all time even though they only cost 6 dollars.
