Are you near a Walmart grocery? They carry it. I get mine at Winn Dixie.
If you have to order it, Bob's Red Mill carries it.
yes i have a walmart, but my walmart doesnt carry it. there backing section isnt very big. i live in puerto rico so you cant find some things here that you can over there. one of the bad things here and to order can be a pain sense they stopped doing free shipping here on amazon and there shipping can be a bit more expensive too.
