The link from the fertilizer article was broken.
I have had some time to think about it, and one thought that I had was meat packers (it is used to cure meat). Another was farm supply stores (it is a fertilizer). Finally, I thought of gun shops (a component of gunpowder).
I am at work, and cannot tie up my phone right now to call around. Has anyone tried any of these?
