Walmart offers the Mainstays 17-oz. Stainless Steel Double Wall Sports Bottle in Red Pepper or Green Ombre for $8.83. Opt for in-store pickup to avoid the $5.99 shipping charge. That's the lowest price we could find now by $5, although we saw a 2-pack for $3 less in December. It features double-wall vacuum insulation and a twist-on cap.

Want a different color? It's available in Teal Splash, Stadium Blue, or Red Ombre for $9.21, Teal Ombre for $9.23, or Blue Ombre for $10.21, all via pickup.
