Walmart offers the Wahl Mustache and Beard Trimmer, model no. 5537-420, bundled with a Nose and Ear Trimmer for $7.69. (With orders of $25 more, Amazon offers it for the same with free shipping for Prime members.) Choose in-store pickup to avoid the $4.97 shipping fee. That's the lowest total price we could find by $7, although we saw it for $2 less in May. It features a five-position guide, high-carbon steel blades, and storage base.
