H there!! I found a place where you can get all sorts of the coolest supplements, minerals, kelp, diatomaceous earth, etc. that you can't find anywhere else, it seems. If you live in Indiana and want the name and number to this person, PM me and I'll send it to you. I can tell you that the DE was $20 for a 50# bag and it is food grade, of course. That is a great price. He has a warehouse with loads of stuff so you could actually make the trip and stock up on stuff. It would be worth driving the miles if you got everything you need for quite a while. It is only about an hour or less from my house. Let me know if you are interested!!
