Walmart offers the Panasonic Wet/Dry Beard and Hair Trimmer for $19.99. Opt for in-store pickup to avoid the $5.99 shipping fee. That's $5 under our June mention and the lowest price we've seen. (It's the best deal now by $18.) It features 19 trim settings.
Note: It won't be ready for pickup before Christmas.
These retailers offer some of the most consumer-friendly price-match policies anywhere.
