As one of its daily deals, Sears offers the Craftsman Digital Multimeter with AC Voltage Detector, model no. 82146, for $14.99. Plus, Shop Your Way Max members bag free shipping. (Not a member? It's free to sign up for a 90-day trial; otherwise, shipping adds $5.99. In-store pickup is also available.) That's tied with our Black Friday mention, $12 off, and the lowest total price we could find. It measures diode and continuity and features seven functions with 20 ranges. Deal ends today.
