In my town (Jackson, TN) which is fairly large (population more than 60 thousand) I have found three 8 quart bags of perlite. I need 5 cubic feet to start with. I have called local nurseries who say they can get big bags, but they're dragging their feet and I've decided to just order some online or try to find somewhere outside of town where I can go get some.

I can get two 4 cubic foot bags for 75 dollars shipped over the internet. Before I go doing that, does anyone know of a place near me that sells it, or another online source that would be less costly?
