Those Brach's stands would also have lots of small bins containing starlite mints, those fruit flavored hard candy sour balls, wrapped in a little twist of clear cellophane, individually wrapped caramels and those strange, chewy coconut candies, and numerous other slightly odd candies. Honestly, I never really liked any of it very much, though I could tolerate the sour balls if I could get a red one.
And I recall that you could "sample" a piece there in store if you dropped a nickel in the little metal box attached to stand. I'd give my kids a nickel for a sample if they went to the grocery store with me, and they'd really try to be happy about it and find something that wasn't gross. But let's face it--they'd really have preferred to just have some Nerds or a Jolly Rancher.
I don't suppose that "Pick a Mix" stuff still exists, though I know I still see Brach's candies in bags, especially jelly beans at Easter time.
Poor Brach's. I guess all the old people who liked their strange candy are now eating it from that dusty candy bowl in the sky...
