Myth: Buy only the items on your shopping list
When it comes to saving money at the supermarket, making a list is the oldest trick in the book. Doing so can keep you focused on foods you need to buy and steer clear of impulsive purchases. However, a list isn’t a guaranteed money-saver. Many stores have weekly deals that can help you save money in the long run. While you should use your shopping list for the basics, you can always take advantage of a great sale if you see one.
