Hi, I have purchased a large sack of pure, food+feed grade diatomaceous earth, the only size which is available to me locally. Since I have much more than I need, and it's hard to locate food grade diatomaceous earth in teeny quantities, I thought I'd pass my savings on to you all. I know the listing is over, but the offer still stands. Please PM me if you are interested. I'm selling 1 Lb of DE for a total of $7 which covers the DE and all shipping costs, Priority Mail. If you would like several pounds, please PM me for details and I can look into packaging / shipping for your desired amount. Because this is a light material, by and large there are no savings to be had by using the flat rate boxes: those things only save lots of money when you're sending something particularly heavy. This diatomaceous earth is E P Minerals' "Celatom" brand, product # MN51, also called Celatom AFA. ("AFA" stands for "animal food additive"; it is a codex, or food grade, product.) Here's a link to their product info , including suggestions on how to use it in organic agriculture as a wormer. One Lb is exactly the right amount to mix with a 50Lb sack of feed for a de-wormer; it's also enough to treat a crowd of chickens for mites. NB, the use of DE for Northern Fowl Mites really does work in my experience. I was as much of a skeptic as anyone. The DE will be securely packaged in a plastic bag, weighed accurately to within .5 gram of 1 pound using a MyWeigh digital scale, and accompanied by instructions and specs sheet from EP minerals. Amounts under 1 pound available also if you just don't want much DE! 10 cents per ounce, plus shipping. Also, if you don't have a good scale of your own, and want the DE weighed out into particular portions, please let me know. Best - exop
