I bet when you find some you buy a significant quantity... It's just the nature of the beast - stuff gets scarce, you spend too much time trying to find it, then when you do, you buy more than you would have otherwise. Multiply that behavior times the whole market, and the scarcity builds until prices get so out of hand that very few are buying. Then things will moderate. Availability will start to improve (because no one is buying, but manufacturing continues) and prices will slowly start to come down because there won't be a renewed rush to buy (barring external changes) due to availability. Prices will finally settle, probably at a 10-20% increase over what they were in 'the good old days' - and then, my friend, is the time to stock up, because it will all happen again.
I've seen this cycle way too many times in the powder-burner world, and now it's hitting airguns as well, though probably due to other factors (covid shut-in, higher consumption of magazine fed guns, etc). Looks to me like PB ammo and components have reached peak-stupid and stock is starting to return. I don't think pellets have reached their zenith yet, but it doesn't seem far off. But first, stupid high prices...
I wish you luck in finding enough to weather the storm, but it will pass...
