Dirt Devil takes up to 60% off a selection of new and refurbished vacuum cleaners, air purifiers, cleaning solutions, and more during its Friends & Family Factory Sale. (Enter password "FRIENDS2014" to see the sale.) With free shipping on all items, that's the first such sale we've seen from Dirt Devil, yielding many significant price lows. A 1-year Dirt Devil warranty applies to refurbished units. A couple best bets: Note: Many items are "new in box" with a damaged box but still have full warranties.
