Sears offers the Craftsman C3 19V Lithium-Ion Drill and Circular Saw Combo Kit, model no. CK2011, for $79.96 with free shipping. That's tied with our mention two weeks ago, $80 off, and the lowest total price we've seen. The 3/8" drill/driver features a 24-position adjustable torque clutch; the 5.5" saw has 0° to 50° bevel cut capacity.
