As in many other industries, appliance sales have suffered as the U.S. economy has slowed and consumers spend less. Major-appliance shipments declined 7.4 percent for the year through August, according to the Association of Home Appliance Manufacturers. But there's one bright spot in the market: stand-alone freezers. Shipments of freezers were up 3.5 percent for the first eight months of the year and rose 13 percent in August over a year earlier; upright models saw an annualized sales jump of nearly 17 percent in August; chest models, 10 percent.

Rising food prices could be a factor in the growth of freezer sales. From 2005 to 2008, the overall cost of food for home consumption was projected to climb 4 to 5 percent, according to this Wall Street Journal report. The ever-increasing tab at the checkout line has spurred more Americans to buy in bulk at warehouse clubs such as Costco and Sam's Club, likely creating a need for more freezer space.

If you're considering getting a stand-alone freezer, use our buyer's guide to get the right unit for your needs. Avoid placing the freezer in the garage, where fluctuating temperatures can force the compressor to work extra hard. If you find that after a while you're not using your separate freezer, consolidate frozen foods in your primary refrigerator-freezer and turn off the stand-alone freezer.

As for what goes into the freezer, don't fill your new appliance with high-fat, high-calorie foods. As we reported in the July 2008 "Can Appliances Make You Heavy?" kitchen appliances could encourage poor eating habits. (Some freezers have dedicated storage compartments for pizza and ice cream, for example.) Visit ConsumerReports.org/health for diet and nutrition advice.—Daniel DiClerico
