Natural Food stores...so they sell food as well. I think that is the difference between them and GNC.
Also you can try searching it and buy it online too and maybe some natural food stores in your area. They are bound to have it, it's good stuff.!
The ice oh just thinking about it now makes my mouth water but I know if I tried crunching it now it would make me cringe. I could not live without the stuff! Brown sugary flavored ice, nom nom!
