What the greatest discontinued candy bar of the 1970s?
…that would have to be the Marathon Bar! It was a braided piece of chocolate with a chewy, caramel center. Alas, it vanished from shelves around 1980 (if I remember correctly). *sniff* Okay, so it might not be the “greatest” candy bar of the 1970’s, but it sure was tasty and it is certainly discontinued.
