Stole this from the guys over on the NW Region sub-forum
Palmetto State Armory has CCI 36g Mini-Mags or 40g Standard Velocity for $6.99 per 100. All the shelves of my local retailers are empty of .22 LR ammo. PSA has this very high quality ammo at "non-capitalistic supply-demand curve-driven" prices.

I just ordered a couple 1000.
Wally World in western Pennsylvania has stacks of them. (Grove City store)
