Interesting. You all either hit on the very top sellers or the poorest performing candy bars.
Top bars: Hershey's, Snickers, Reese's, Butterfinger, Kit Kat, etc
poorest performers: Bun, Skybar, Payday, Symphony, Oh Henry!, Baby Ruth, and the long defunct Marathon
No one even mentioned Almond Joy, Mounds, Caramello, York Peppermint Patty, Heath, Milky Way or Nestle Crunch; all top sellers of the past.
For pure milk chocolate, the Dove bar is wonderful. (The Symphony bar was very similar.)
There are few I don't like which might explain my waistline.
