Taco Bell had 3 for a buck in 1992.
We had a drive-in that sold the square burger for 15c.
The big burger with cheese was .45 same as McD.
I know these prices because this is how I measure inflation.
It is McDonalds economics.

They stopped selling tacos 3 for a dollar when people would order two tacos and the clerk’s heads would explode trying to figure out how much to charge.
