Lowe's offers the Kobalt Universal 8-Piece Standard Oxide Metric Wrench Set in Black for $19.98. Plus, MyLowe's members get free shipping. (Not a member? It's free to join.) That's tied with our June mention as $10 off and the best price we could find. It includes 8, 10, 11, 12, 13, 14, 15, and 17mm wrenches. Deal ends November 29.
