Sears offers the Craftsman 250-Piece Mechanics Tools Set, model no. D391790, for $149.98 with free shipping. That's $150 off list and the lowest total price we could find, although we saw it two weeks ago for $12 less. It comes in a 3-drawer case and features a range of drive sockets, extension bars, combination wrenches, and magnetic screwdriver bits.
