Shoppers looking to take advantage of bargains should beware if they have carbon monoxide alarms in mind. As a result, some manufacturers dumped tens of thousands of obsolete alarms on the market at bargain basement prices for the holidays.

Consumers have one way to make sure they are getting an alarm that meets the new standards.
