Every month the editors of Washington Consumers' Checkbook magazine report some of the best prices they have found in surveying more than 300 area retailers.

The retailers have promised to hold these prices -- and offer rain checks if supply runs out -- until Jan. 31. Call ahead to check that a product is in stock. Tell the retailer that you want the price quoted in "Checkbook Bargains."

Here's a partial listing of bargain prices based on Checkbook's survey.
