Check out: grillstuff.com. They sell Ozark Oak for $9.95 per bag and they offer free shipping on orders over $99. I ordered 20 bags (200lbs) a couple months back and it came in 4 big boxes and shipped for free. Not sure why they haven't figured it out yet - but they must be loosing money offering free shipping on a $9 bag of lump.
Ozark Oak is very good quality. Check out the naked whiz to see his comments.
