My point was more that it isn't something people are likely to already have on hand at home. It's certainly readily available and extremely cheap for this purpose, but you need to actually buy some before a disaster hits.
You can often find it in the spice section. People use it to make pickles.
McCormick/Schilling sells it, among other major brands.
Walmart sells "Hoosier Hill Farm" brand for about $15/pound.
