Ironbark is right, head down to a bulk store and buy a 20l drum, lasts forever
With regard to molasses, go down to your local ag shop or stockfeed store. I use it on the garden and from memory I got change out of $30 for a 10 or 15kg tub last time, but probably gone up since then. most good stockfeed store will have a 44gal drum full to decant
