All places may not have what your looking for at a particular time so I'd call around. I'm sure there are more but these are all I know about.

Wow, impressive resource list, well done and covering all parts of NC... another fine reason for members to post your location somewhere in your registration info. Let's see your page filled out or something. We'd like to know more about you and your location on your page, as the rest of us are always tapping into this for local resources and connecting with other gardeners, putting this site to use. GW works for me, over and over for 8 yrs now. I wouldnt have done much without it. This post typifies the results anyone can get for the price of admission, which is nothing. I dont know where Dogridge is, but I bet it or they are somewhere in NC. We get our soil conditioners for free here in Forsyth Co. twice yearly in the county giveaway of leaf mold. Great stuff to break up red clay. Personally, I wouldnt have had a garden without it.

Thanks for all of the replies. I'm in the triangle and I found some at AMerican topsoil and mulch. I typically get my soil and mulch from them, but last time I checked they didn't have pine fines. Glad I called again. By the way, American topsoil has a great compost blend that is excellent for topsoil.

Triangle Landscaping has pine fines (soil Conditioner). They are 3 locations in the triangle area.....
