The NHLA site does list quite a few lumber suppliers in NC. As I said earlier, it is not all inclusive because I did not see McEwen Lumber listed and they are in High Point off Prospect St. I have bought from McEwen for several years now for the tablemaking class I teach at John C Campbell. They have treated me well. They will set the unit out for me to pick widths and lengths that best suit the need without excess waste. Not many places will do that for you. I do have a legitimate business with tax number, etc. That may make a difference in the overall picture. Anyway, just trying to be helpful. They are also catering more to the walk-in traffic more than most wholesale yards. They carry sheet goods also.
