I lived in LA county as a kid, born 1961. In 1970 I could buy a candy bar at 7-11 for .10.
The return deposit on a Coke bottle in Los Angeles was .10.
Today in Sacramento the deposit we pay is .8 cents per bottle or can.
The minimum wage in 1970 was $1.60 per hour, that is 16 candy bars per hour then, even though LA had an expensive deposit fee I still found at least 2 a day just riding through a field. Federal minimum wage is $7.25 per hour, in California it is $12.00 per hour, although the TARGET stores recently raised it's beginning wage at $15 per hour! Today a candy bar is $1.89 minimum, that's a bit over 6 candy bars per hour. The minimum wage earner could buy 16 candy bars per hour, today in 2020 in California they can buy 6 per hour with 65 cents remaining. For today's minimum wage earner to be able to buy 16 bars per hour they would be earning $30.24 per hour
It depends on the candy bar.
"No Jelly". It was made for a short time in the 1970's.
That depends on what sort of candy bar it is, where you live, when you buy the candy and in which specific store you shop.
The "Sir Bar" was a chocolate-covered white taffy bar popular in the 1970's. No longer available.
