Most Loblaw stores now have the 50% off pink sticker. If you go to No Frills, Valu-mark, or Superstore you will find products that are close to their expiration date will have this 50% off pink sticker.
The best time to pick up deals is first thing in the morning when the stores open. That is when they go through the store and mark down all the items that are close to expiration date.
Here is what I got from my shop Thursday night on my way home from attending The Tragically Hip Rock Concert* tonight.
