DailySale offers the Panasonic Wet/Dry Nose and Ear Hair Trimmer, model no. ER115, for $18 with free shipping. That's tied with our mention from last week and the lowest total price we could find by $6. It features rotary motion, washable head, and requires one AA battery (not included).
Note: The countdown timer on the product page does not reflect an actual expiration time and resets daily.
