Sears offers the Craftsman 100-Piece Speed-Lok Set, model no. 90587, for $17.99. Opt for in-store pickup to avoid the $7.75 shipping charge. That's $12 off, $2 under our mention from last week, and the lowest price we've seen. It features a quick connector for fast tool changes.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
