WHen I was in college, my final year, 1978, I was in charge of purchasing refreshments for a fraternity event. I got 2 liter coke on sale for a dollar and was proud of the great buy and the money savings.

As I walked down the aisle of my local supermarket in 2018........40 years later.....I am able to purchase on sale either 2 liter coke or pepsi on most weeks for 1 dollar

can anyone think of any other food item that has stayed the same price over the last 40 years??

Yes we all know technology gets cheaper over time. But I am talking about groceries
