Crocs via eBay offers its Crocs Unisex Classic Realtree V2 Clogs in Khaki for $27.99 with free shipping. (Zappos charges the same price.) That's the lowest price we could find by $7, although we saw them for $8 less a year ago. They're available in women's sizes from 6 to 12 and men's sizes from 4 to 17.
