Lowe's offers the Kobalt 20-Piece Standard and Metric Mechanic's Tool Set for $19.98. Plus, MyLowe's members bag free shipping. (Not a member? It's free to join.) That's tied with last week's mention, $30 off list, and the lowest price we could find. It includes an extendable handle and an assortment of sockets and bits. Deal ends February 6.
