If they are old enough to have that price tag, they are probably 14 oz. cans instead of 12 oz. cans as typically seen now. It's really interesting to see what is called a one pound can having only 3/4 pounds inside.
I remember in the seventies it was very common to see R12 cans at Target or KMart for $.59 each.
I wouldn't let my blood pressure get out of control over this. It's only your congress at work, coupled with good ol' supply and demand free enterprise at work. It beats socialism by a country mile.
Have a great day,
