I remember a couple prices vividly when I was around 5 years old (sometime back in the 60's)...
My dad bought stamps for his letters, 3 cents each.
My dad gave me a one-gallon gas can and had me walk to the gas station some three or four blocks away (by myself), 33 cents a gallon (he gave me 35 cents and told me to bring back the change).
Oh, and the Five and Dime store, most everything was 5 cents and 10 cents and not just candy. You can't find that anymore.
I remember my dad buying those plastic army men for me and I think they were like 2 for 5 cents.
Sure do miss those days my friends.
