I am not sure if this is the right place to put this post, mods please move it if it needs moved.... I have looked at all the feed stores in my area for DE and none of them had it and really not many of them even knew what I was talking about. However, one lady at one of the feed stores suggested I call the local plant nursery. I did and they carry it, so if you can't find it, this might be a place for you to look. It is food grade. Just wanted to pass this on, I didn't want to pay shipping and now I don't have to. I am happy!
