Homie Deals via eBay offers the TC Clog Brand Unisex Nursing Clogs in four colors (Navy pictured) for $5.99 with free shipping. That's tied with last week's mention and the lowest total price we could find by $6. They're available in sizes 8 to 11, although not in all size/color combinations. (Note that select sizes may show at a higher price.)
The planet will thank you, your local (overwhelmed) landfill will thank you. Even your budget will thank you.
