(Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $6.29.) Excluding the below mention, that's the lowest total price we could find by $2, although we saw it for $2 less in December. It features double-wall, vacuum-insulated stainless steel that keeps beverages hot for four hours or cold for 12 hours. The lid is made of BPA-free plastic.
