Freezer sales rose last spring, as more Americans apparently made bulk to purchases to stretch their food-buying bucks. But an inefficient freezer that delivers inconsistent temperatures will melt away your savings through higher electric bills and damaged food.

Our new video buyer's guide to freezers (right) details the strengths and weaknesses of some popular models of chest and upright freezers we tested. For more details on these appliances, check out our latest report on freezers, free buyer's guide, and ratings of 20 models (available to subscribers).

Once you've chosen a model, find the best places to buy appliances. Also be sure to take advantage of federal, state, and local governments tax incentives and rebates for freezers and be on the lookout for details on the $300 million State Energy Efficient Appliance Rebate Program, commonly called cash-for-clunkers for appliances.—Gian Trotta | e-mail | Twitter | Forums | Facebook
