Walmart offers the Stansport Cast Iron Cooking Tripod, model no. 15997, for $18.09. (Amazon charges the same for Prime members only with free shipping.) Opt for in-store pickup to dodge the $5.99 shipping fee. That's the lowest price we could find by $13, although we saw it for a buck less in January. It features heavy-duty solid steel construction, adjustable height, and a foldable design.
