Aokon via Amazon offers its Aokon Kids' Long-Range Walkie Talkies Watch Set for $21.66. Coupon code "SJ6RC2J9" cuts that to $16.24. Plus, Prime members receive free shipping. That's the lowest price we could find by $5. They feature a magnifier, night light, and up to a 3.7-mile range. Deal ends January 15.

Note: They have a compass, but it is for decoration only and doesn't function.
