Woot offers the Black + Decker 12-volt Flexi Automotive Vacuum for $24.99 plus $5 for shipping. That's the lowest price we could find by $10, although we saw it for $3 less in July. It features a 12-volt cigarette lighter adapter, flexible hose, 2-in-1 flip-up brush/wide nozzle tool, long crevice tool, and 16-foot cable. Deal ends September 6.
