- You can save nearly every leftover from every meal for a much longer time than if you covered them with plastic wrap, because the lack of air in the sealed bag prevents spoilage. No more fuzzy meatballs in the back of the refrigerator!
- You can cook meals in advance, seal them, store them in the freezer and pull one out whenever you need, eliminating a trip to the grocery store or a restaurant bill if you have nothing fresh on hand. You can create a week's worth of dinners in a weekend and eat them six months later.
- You can buy food in bulk at a much lower cost, divide it into portions and freeze. When that whole tenderloin goes on sale, you can cut individual steaks and have them on hand for a year or more.
