http://www.7springsfarm.com/catalog.html#DE%20animal I never thought of ordering DE from here. I thought about it today and looked, sure enough they sell food grade DE. I have ordered other organic crop products from them in the past. Even with a large weight the shipping has been very reasonable in the past. You can email him for a shipping quote, I would think it matters where you are in relation to them. Just thought I would post it as a source.
