If you want 8# jugs you will have to have it ordered special, from your local gun store, probably will have to pay for it in advance too,try MIDSOUTH SHOOTERS SUPPLY...
Last year I saw a jug in a shop in Athens. Haven't seen any 8lbs anywhere else besides online. Save your pennies and eat the hazmat fee but tack on primers or other powders you want to try. I think @shotgun 01 had a jug he was considering parting with at one point.
