Crocs offers its Crocs Unisex Classic Sandals in Black, Espresso, or Navy for $26.99. Coupon code "EXTRA50" cuts that to $13.49. With $4.99 for shipping, that's $17 off list and the lowest total price we could find, although we saw them for a few cents less in July. They're available in men's sizes from 4 to 13 and women's sizes from 6 to 12, although not in all size/color combinations.
