Where are the cheapest places to shop for food in Los Angeles?

As you can see by all of these replys there is no one place with the lowest prices. You have to use due diligence by checking newspapers and your mail for sales on what you need. Clipping coupons will help as long as you don;t buy something just because you have a coupon. I might add one tip, don't go shopping hungry, everything looks so tasty you end up buying too much.
