If you already grocery shop with cash, then you are ahead of the game. If you are not used to it, try it. First, check sales where you will be shopping and make a grocery list of the things you need. Invest in a cheap calculator and go to the store with enough cash to cover your food budget. You might take a little extra in case you want to stock up on something on sale. When you are limited by the cash you bring, you are challenged to use your creativity and buy only what you really need. Using cash can be a great money-saver!
