    Smoke detector batteries go out almost at the same time. Buy this pack to save on money and gas on one trip for the whole house.

    Found these on a "Deal of the Day." Price was excellent and since 9 volt batteries are an essential homeowner staple (smoke detectors...), I could not pass up the deal. The quality is equal to the top brands at less than 1/2 the price. Thank you Best Buy! P.S. Loved that the discount offer was posted just two weeks before the time change.
