Sears offers the Craftsman 12-volt Portable Tire Inflator, model no. 75120, for $44.99. Opt for in-store pickup to avoid the $9.50 shipping charge. That's $10 off list price and the lowest total price we could find, although we saw a shipped inflator for $6 less in January. It features a 15-foot air hose, 8-foot power cord, pressure gauge, seven inflation accessories, and LED light.
