World of Optics via eBay offers the Oakley Men's Madman Polarized Sunglasses in Pewter/Black for $119.99 with free shipping. That's the lowest price we could find for any color today by $43 (excluding other eBay vendors), although we saw them for $30 less two weeks ago. They feature 100% UV protection, a diecast aluminum / O Matter frame, impact-resistant Plutonite lenses, and hydrophilic Unobtanium nose and temple pads. They come with a MicroBag and Madman case.

Note: These sunglasses will arrive in a sealed retail box, but the box may have minor scuffs or creases from storage.
