Walmart offers two Ozark Trail 30-oz. Tumblers
in Stainless Steel for $9.24
. (Be sure to select this color option to get this price.) Opt for in-store pickup
to avoid the $5.99 shipping fee. That's $4.62 per tumbler, a buck under the per-unit price of our mention from earlier today, and the lowest per-unit price we've seen. Each BPA-free tumbler is double-walled and vacuum-sealed.
