10. Shop With Cash
I know I know, who shops with cash? I do. It helps me evaluate the weight of my purchases (mostly because I have no weight left in my wallet after!) and make wiser choices. If you shop with cash (no cheating by using your debit for overages!) you will ensure that you stick to your list and be less wasteful. Are you going to buy those $6 cookies or buy enough ingredients to make your family dinner?
