Homie Gear via eBay offers its Homie Gear Men's Benassi Summer Slides in Black for $5.99 with free shipping. That's $14 off list and the lowest price we could find, although we saw them for a buck less last August. They're available in sizes 8 to 13. (Sizes 14 and 15 cost $2 more.)
Note that these will ship in a bag, not in a box. Additionally, the seller recommends that you order one size up to ensure a proper fit.
