Crocs offers its Crocs Unisex Duet Athens Flip Flops
three colors (Ocean/White pictured) for $19.99
for shipping. That's the lowest total price we could find by $2. (For further comparison, we saw them for $10 less with the purchase of any pair of non-sale Crocs' shoes in August.) Sales tax is added where applicable. They're available in men's sizes 4 to 13 and women's sizes 6 to 12, but not in all size/color combinations.
