Re: If you buy diatomaceous earth- food grade, where?
I recently got my first bottle of DE from Nature's Wisdom on amazon. I shopped around, and I could get large quantities cheaper, but for the trial quantity I wanted (2.5 lbs) that was really the best. However, if you think you will only want a small amount, you can get smaller amounts (slightly cheaper but not cheaper per ounce). After determining if DE is a good program for me, I would probably get it in bulk from earthworks once I check out their shipping price (for modest amounts like what I got, it was more expensive with shipping than amazon).
