Best Buy offers the Panasonic Wet/Dry Nose and Ear Hair Trimmer in Black/Stainless/Blue, model no. ER-GN30-K, for $9.99. Opt for in-store pickup to avoid the $5.49 shipping charge. That's tied with our June mention and the lowest price we could find by $5. It features a dual-edge blade and Vortex water cleaning system. One AA battery is required, but not included.
