Kmart offers the Craftsman Stud Finder with SpotLite Pointing System, model no. 41588911, for $10. (Opt for in-store pickup to avoid the $5.99 shipping fee.) That's $10 off, $5 under our mention from last summer, and the best price we've seen for this item. It can locate edges of wood and metal studs through drywall and other common interior surfaces up to 1-1/2" deep and features two detection modes.
Of note, Shop Your Way Rewards members will earn a Kmart credit with this purchase and may be eligible for additional credits and discounts.
