Walmart offers the Tramontina Cast Iron 6.5-Quart Dutch Oven in four colors (Red pictured), model no. 80131, for $39 plus $4.97 for shipping. (Site-to-Store pickup is also available.) That's the lowest total price we could find by $17, although we saw it for $5 less a year ago. This cast iron Dutch oven features a porcelain enamel interior.
