Cool. I may be a rare bird but I love this nerdy math stuff. The bank of Canada actually has an inflation cluculator on-line:
https://www.bankofcanada.ca/rates/related/inflation-calculator/
In running a couple of prices through it:
Soundwave: $16.66 in 1985, should be $39.93 in 2022
Optimus Prime: $24.44 in 1985, should be $58.58 in 2022
Astrotrain of Blitzwing: $12.88 in 1985, should $30.87 in 2022
Make of those prices what you will. They seem low to me based on what I'd expect a re-issue to cost but not by as much as I thought.
