Grocery on a Budget with Woolworths Weekly Specials at 50% Off

Since I found out that a few grocery stores regularly have special sales for selected items every week, I make it a point to time my weekly grocery shopping on the first day of these sales. For the next week starting Wednesday, the items from the following brands are on sale for as much as 50% off: Dettol, Eveready, Nestle, Finish, Olay, L'Oreal, Omo, McCain, and Nescafe. There are also fresh meat and seafood on sale. I'm surely going to stock up on Nescafe Gold Blend Coffee for which the 200g pack costs $4.30 less at $10.99 each, and my L'Oreal Elvive Shampoo and Conditioners where two 250ml bottles will just cost $8.
