In spite of clear state commerce laws, I don't think I've ever seen a price for a cord (4ft high x 4ft wide x 8ft long) of wood around Chattanooga. People sell by "face cord", "rick", or "truck load". A face cord or rick is usually 4ft high x 8ft long, but the stick length can vary from 12" to 18". There's a place in Red Bank (north of downtown) that sells about 1/3 cord of good split oak (16" sticks) for $75, so a full cord would run $225. They also sell other types of wood, such as hickory or apple for smoking. They load it in your vehicle, but you must transport and unload it. I can carry 1/3 cord in the back of my regular-bed Silverado (no tool box).
You can also find people selling "truck loads" of wood. They park around town with signs advertising the prices. The Bi-Lo on East Brainerd seems to be a popular place. The unit price for wood purchased this way can be much higher. It usually runs $50-$75 per truck load, but load size can vary considerably depending on if the wood is cleanly stacked or randomly tossed in, and on the size of the bed. Also you'll want to pick up a few sticks to make sure they didn't fill the truck with rotten or green wood then cover it with a layer of good split oak as dressing. One advantage to buying it this way is that the seller will usually deliver to your house, so this may be the only way to go if you don't have access to a truck.
