The closest place to me that had it available at all was an Ace Hardware about 40 minutes away, but they never stocked it and could only order the small Manna Pro 5 lb bags for me from their supplier. Costs almost $20 for two little bags, but soon I'll be able to buy big 25 lb bags of it for much less. Home Depot has giant bags of perlite for $17, so I've been using that a lot but the winds here just blow it away when it drifts to the top. But no more! First day they open I am cleaning out their stock of it!
