it's an extra 10% off. it expires on the Jan 22nd, though.
i find codes for them are really rare though.
and Swanky, Otticanet is a online sunglasses retailer, that has designer sunglasses at some of the lowest prices i've seen, plus US customers don't pay tax or customs duties! and if for some reason you get billed for customs, like i did, you just fax/scan the bill and they refund you right away.
i've ordered from them before and they're super sweet, and i can testify that their sunglasses are completely authentic, and have nothing but positive transactions.
