Amazon offers Prime members the Panasonic Vortex Wet/Dry Nose and Facial Hair Trimmer, model no. ER-GN30-K, for $9.99. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping adds $5.48.) That's the lowest total price we could find by $5, although we saw it for $1 less in December. It features a dual-edge blade and requires one AA battery (not included).
