Use the 10% Rule

I call this "the 10% rule". Whatever you are using, try using 10% less: 10% less laundry detergent, 10% less shampoo, 10% less toothpaste, 10% less hamburger in your casserole. Chances are, you won't even notice that 10% is missing -- and saving a penny here and a penny there DOES add up!
