That's what they STILL should be. I don't pay $4 for ANY BP 18mm runt motors.
Last time I bought any 18mm BP SU motors was 18paks of C5-3 through AC Supply for $7.49 a pak 2 years ago, and I thought THAT was too high.
$0.25 per n-sec is ABSURDLY HIGH.

Huh. Thought you were a believer in capitalism...

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:

The other day I sat next to a woman who has a profound fear of flying. I wanted to comfort her, so I said, "Don't worry, we're not gonna' crash. Statistically, we got a better chance of being bitten by a shark." Then I showed her the scar on my elbow from a shark attack. I said, "I got this when my plane went down off of Florida." - Dennis Regan

To add a bit to Winston's post, there have been massive changes in government regulations in the last 50 years - I doubt any of them have made dealing with potentially hazardous materials (i.e. black powder) cheaper or easier.
Heck, I'm pleased and a little surprised that the feds haven't come up with a reason to increase regulation of model rocketry to the point of making it unviable (remember they tried with AP motors back around the turn of the century)...

Rocket motor prices have went from "Too High" to "Outrageous/Absurd".
Large factor in why I have moved back to a lot more R/C aircraft activity.
Initial cost for R/C glow or electric power aircraft is much higher than anything LPR or MPR, but the cost per each MUCH longer (and controlled) flight is much lower.
If my AMA club did not require rocketry flight under the NAR safety code, I'd equip my 1/11 scale F-4 with actual FIRING Sidewinders.
When in doubt, WHACK the GAS and DITCH the brake !!!

Yes, there is such a thing as NORMAL
, if you have to ask what is "NORMAL" , you probably aren't !

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
