Sears offers the Craftsman 8-Piece Impact Drive Tool Accessory Set, model no. 15358, for $34.99. Opt for in-store pickup to avoid the $5.99 shipping fee. That's $15 under our September mention, $35 off list, and the lowest price we could find. It features five extension bars for 1/2" and 3/8" drives, 3/8" and 1/2" universal joints, and a 1/2" to 3/8" adapter.
