The pricing comments here got me curious.

Estes 1970 catalog:

In 1970:

C6-5 3-pack $1.20
D13-5 3-pack $2.00

Using an online inflation calculator which uses the (BS-low since 1980) official inflation rates over time: $1 in 1970 = $8 in 2023.

Using that, in 2023:

C6-5 3-pack should be $9.60 (is $12.99)
D12-5 3-pack should be $16.00 (is $13.49 for 2; which would be $20.24 for 3)

That's close enough considering the difference can probably be explained by the huge CPI figure fudging via the changes in the method of calculation and items included which has changed significantly, primarily since 1980 as can be easily seen in the lower graph shown here:

BTW, from that you can see that when someone compares official inflation figures now with the past, they are comparing apples and oranges which shows you how many "experts" aren't.

How the fudging is done:
