Anyone know of a retailer that sells on the East US coast?
Better yet, anyone near Buffalo, NY?

I really want to get my hands on the substrate but am having a difficult time trying to find some.
I'm going to visit my LFS and ask about the possibility of them stocking the stuff, but I won't hold my breath.

I am familiar with the following internet retailers based out west, but shipping 80 - 100lbs of substrate gets expensive quick.
