Available for pickup only and with stock varying by ZIP code, Sears offers the Magnetic Mount 12-volt Power Light, model no. 10716, for $1.97. That's tied with last month's mention as the lowest total price we've seen. (It's a current low by $6.) It features a 10-foot retractable power cord and a 10-watt bulb.
Of note, Shop Your Way Rewards members will earn a Sears credit with this purchase and may be eligible for additional credits and discounts.
