Buy your cheese in the dairy aisle and not the deli and you could save up to 30 percent since you're not paying someone to slice it for you. Buy your oranges, onions, and potatoes in the bag and not individually and you'll pay half the price.

Real Simple magazine lists some other supermarket-saving tips in their May 2008 issue. Like this: Purchase your seafood frozen, not fresh, and you'll be 20 to 40 percent richer. Remember this: Most "fresh" fish has been frozen for transport so essentially, both options are very similar.

Buy ground beef and chicken in bulk or in family portion sizes. You'll save about 20 percent on beef and 50 percent on chicken by going this route. And don't buy non-grocery items in a supermarket. Pick up your health and beauty items, for example, at Target or other mass marketers. They're cheaper at these locations.
