Pepsi Next 2L's been selling for a dollar at Foodworks Granville since about a week ago even though the flyer says otherwise.
If you're gonna be getting charcoal from El Jannah or Awafi, could stop by and make the most out of your petrol/ticket to buy a bottle or three. Though the bottles are marked to expire on the 5th of March.
EDIT:
Forgot that they have PayPass so ING Direct 5% works there!
Cheaper at IGA Merrylands West 59¢ for 2lt bottle
