Wow. I just looked it up. Arkansas has a standard. Cords or fractions thereof, since 2001. The standard is not enforced. 99% is sold by the “rick”. Occasionally by the truck load or pile. I’ve never known it to be sold by the cord.
In the land of doublespeak you pretty much have to. I see a few people selling 128 cu ft cords like there are too many different kinds. Whether actually they know what a 128 cu ft cord is might be an unknown.
