    With deals on items as varied as electronics and back-to-school supplies, September is a surprising month for good buys. Pick up reasonable prices in these departments:

    Mattresses. Year after year, September is the time for mattress sales. Expect these from department stores and mattress centers, usually as a part of Labor Day deals.

    iPhones. Apple has been known to announce its new iPhone installments at the company's annual keynote in September. Usually, the unveiling is followed by a drop in prices on the current phones in anticipation of the new models.

    Appliances. This year, Labor Day falls on Sept. 4. Expect a series of blowout deals in the week leading up to the holiday, including promotions on appliances big and small.
