Sears offers the Craftsman 1/2" 19.2-volt Cordless Impact Wrench, model no. 31305, for $89.99 with free shipping. That's $50 off list price and the lowest total price we could find, although we saw it for $10 less in October. It provides 200 foot-pounds of torque and up to 3,000 impacts per minute. Deal ends April 30.
