6pm offers the Dr. Martens Unisex Ade Elastic 3-Eye Shoes in Charcoal Perfed Canvas (pictured) or Black Perfed Canvas for $39.99 with free shipping. That's the lowest total price we could find by $5, although we saw them for pennies less in August. They're available in women's sizes 8 to 11, and men's sizes 7 to 13.
