Walmart offers the Ozark Trail 30-oz. Stainless Steel Tumbler, model no. 83-461, for $9.74. Opt for in-store pickup to dodge the $4.97 shipping charge. That's tied with our mention from two weeks ago and the lowest price we've seen. (It's also the best deal now by $10.) It's BPA-free.

Of note, you can also get the 20-oz. version, model no. 83-462, for $7.74 via in-store pickup. That's also tied with our mention from two weeks ago and another price low, this time by $19.
