Walmart offers the Mossy Oak 20-oz. Stainless Steel Straight Mug in Matte Black for $7.94. (Amazon has it for the same as an add-on item.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's $2 under our September mention in stainless steel, $3 off, and the lowest price we could find. It features a screw-top slide lid.
