Shop the discount section first.

This works for so many reasons. If you find something you were going to purchase in the discount section, pick it up. Then when you are in the regular aisle, you can check the price to see if it's a discount at all. While in the meat and produce mark-down areas, you may even want to readjust your menu and shopping list because of major sales. Four wilting peppers won't last until next week's menu but sure would make a great stuffed pepper dinner tonight.
