Vitamin water at sobeys?

HEY im trying to find the flavour of vitamin water that i think is called "mega-c" or "power-c". its the dragonfruit flavour. i live in canada but i dont know where to get it in packs! like a four-pack, or something similar. does anyone know where to get them? do you know if you can get them at sobeys, loblaws, no frills, anywhere else?! THANKS
