Walmart offers the Mainstays 17-oz. Water Bottle 2-Pack in Berry/Gold for $6.57. Opt for in-store pickup to cut that to $6.30. That's a buck below our mention from last week and the lowest price we've seen. (It's the best deal now by $13.) They're double walled.

Select stores may have pickup availability before Christmas. (Choose "See more stores" on the product page to see pickup dates for each store.)
