I buy food as I find it. if I find some on sale I like Ill buy it or if I hear a recommendation I buy it.
I have NLS pellets, rods, frozen mysis, 3 different flakes, cyclopeez, and a couple others I don't remember the name to. I probably have enough food to last the rest of the year. If not longer.
are you looking for specific brands? large quantity orders?
I have bought food from petsmart, Aquarium adventures, tropiquatics, AP, etc.
