It's not originally a Hershey's product but it's theirs now. I bought a bar from a local drugstore for $1.
I'm not sure why it's called a "Zero" bar; then again, I don't know why a Kit Kat is called a "Kit Kat" either. Still, the name "Zero" makes you think it might be a low-calorie, no-sugar, or something. It is none of those; just your typical but non-chocolate candy bar.
The caramel just adds more sugar to an already cloyingly sweet candy bar.
