Sears offers the Craftsman 100-Piece Drill/Driver Accessory Kit, model no. ACM1001, for $12.99. Opt for in-store pickup to dodge the $7.75 shipping fee. That's $17 off list and the lowest price we could find, although we saw it for a buck less two weeks ago. It features Phillips and flat driving bits as well as drilling bits.
