A best bet is the Crocs Unisex Baya Slide Sandals in Espresso, Black, or Navy (pictured) bundled with the Crocs Unisex Duet Athens Flip Flops for $34.99 with free shipping via the above coupon. That's the lowest total price we could find for this combo by $12. Both are available in women's sizes 6 to 12 and men's sizes 4 to 13, although not in all size/color combinations.
