About the time our big supplier took their lousy acet generation off line to replace it the shortage came up. I remember when mag went up, first the major US stockpile burned for two weeks and then one of the largest mfrs went up. Price went triple in months.

Never knew why the price jumped, just know that it did. I had chalked it up as similar to comparable fast price jumps in copper/lead/scrap in general (especially resulting wholesale batteries and tire prices) about a decade ago.
