A U.S. comic book costs $3.99 or $4.99 dollars today. In 1940's, comic books costs 10 cents. In 1990's, it costs only $1 dollar.
I went to use an inflation calculator. https://westegg.com/inflation/infl.cgi
What cost $1 in 1990 would cost $1.98 in 2019.
Also, if you were to buy exactly the same products in 2019 and 1990,
they would cost you $1 and $0.49 respectively.

According to another inflation calculator, $1 dollar in 1990 would be worth $2 in 2020.
How did they increase the price of a comic book four times in thirty years from 1990 to 2020 when the comic book should be be only $1.99 dollars in 2020, only two times the price in 1990?
