Soil availability

I'm looking to use Fox Farms Ocean Forest for my grow since many posts seem to recommend it. However, I'm not sure where to get it. Do any major store chains carry it? I checked Fox Farms web page and the closest places they list are 2.5 hour drive from me. Specialty shops are few around here also.

Search for hydro supply, like hydro supply near (zipcode) in Google.

Nothing within 50 miles. Looks like I'll be making a long drive (calling ahead first). I'll stock up if the stuff will keep awhile in sealed bag.
