Big difference between what something is worth, and what people will pay.
A few years back when all the hoarding of primers was taking place, the world got to see what people would pay.
I kept some 1 lb powder containers with price tags of well under $2.00 bought in the 70s. I remember well buying a 20# container of H870 for $20.00 in Butte Mt. in the mid 70s.
