Sears offers the Craftsman 100-Piece Drill / Driver Accessory Kit, model no. ACM1001, for $12.99. Opt for in-store pickup to dodge the $3.99 shipping fee. That's the lowest price we could find by $11, although it was about 50 cents three weeks ago. It features Phillips and flat driving bits as well as drilling bits.
