Every month the editors of Washington Consumers' Checkbook magazine report here 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 rainchecks -- until July 31. It is a good idea to call ahead to check that a product is in stock. Explain to the retailer that you want the price quoted in "Checkbook Bargains." Stores may limit purchases to one per customer.
