Not me. I remember getting caught in the 90s when the first panic struck. There wasn't a primer, mag, or powder to be had. From then on, I always kept at least a year ahead.
After the panic, everything will be available again, but it might take a year. How many times has this happened? I'm thinking 3 or 4, and each time seems worse. I remember 4 years ago it happened. When things normalize, and the prices come back down somewhat (never goes back to what they were), get your stash built.
I'm getting older, and would like to get a lifetime's supply built, if I can afford it.
