As one of its daily deals, Best Buy via eBay 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 $7.98 shipping charge. That's the lowest price we could find by $2, although we saw it for a buck less three weeks ago. It features a dual-edge blade and Vortex water cleaning system. One AA battery is required, but not included. Deal ends today.
Of note, Amazon offers it for the same price for Prime members.
