Amazon offers the Black + Decker 12-volt Flexi Automotive Vacuum for $27.49 with free shipping. That's tied with our mention from two weeks ago and the lowest price we could find today by $11. 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.

Note: You can also opt for free no-rush shipping to bag a $5 Amazon Prime Pantry Credit.
