For Prime members only, Amazon offers the Withings Thermo Smart Thermometer for $79.95. Clip the 25% off coupon on the item page to drop it to $59.96. With free shipping, that's the lowest total price we could find by $20, although it was $2 less two weeks ago. This contactless thermometer has 16 infrared sensors that take more than 4,000 measurements to find the hottest point, and promises to deliver accurate results in just two seconds. It can also be synced with a smartphone via the Thermo app.
Orders placed by today (December 16) are expected to arrive by Christmas. (For Prime members, that deadline is extended to December 22 for 2-day shipping.)
