For in-store pickup only, Kmart offers the Craftsman 12-Piece Nutdriver Set, model no. 34555, for $15. That's $5 under our mention from last December and the lowest price we've seen. (It's a current low by $20.) It features a zippered case and color coding for easy identification.
Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
