Why is wd40 so expensive these days?

A large can of wd40 seems to cost like a bomb you'd think it would be like $3 for a large can (not a nozzle tube can) but where I'm from its just insane prices to the point the college I went to to learn automotive were mixing their own form of wd40 using recycled car oil and something else & telling us it's wd40 which probs saved them like 13k a year in costs.. is there like a global share market for wd40 or something which is somehow trying to pay millions of people in shares because it's seeming like it's got liquid gold in it..

Same reason HC is soooo expensive. .

If you want to make it yourself, you would need to run a sample to use a GCMS. And, if you then find out the ingredients, don't expect to pay the same price for volume at Home Depot that the WD-40 manufacturer gets when it buys the ingredients by a tanker car.

Because a lot of R&D went into its development. Water displacement 40 is made to a very specific formula and not just made up with mixing petrol with old engine ils etc etc
