I do know during that time that the biggest part of the price was the cost of the carton. Same with milk, the largest part of the price of milk is the cost of the bottle.
Which is why buying four quarts is more then buying one gallon. More food quality resin and energy is used to blow four quart bottles rather then one gallon bottle.
And the price of a heavy plastic bottle, like with the chugs, really raises the price.
So there you go. More then you ever actually wanted to know about the price of eggs and milk.
When we can, we get eggs locally from the farmers.
We have a milk supply nearby for farm fresh milk.
As a milk fan and former dairy worker I prefer milk in cardboard or dark plastic, since store light causes oxidation and affects taste.
