If you buy in bulk, a food sealer is a smart splurge. You can vacuum-seal meats, fish, cheese, dough and vegetables, which make freezing a breeze. Because of the no-air vacuum seal, your food resists freezer burn. With a food saver, you can keep meat and fish sealed for up to 2 years, where a regular zip-locked bag will only last about 3 - 6 months, at the most. Food Savers start at $179.
