Refer a friend, Get a free trade
You're fashionable (because you wear Sagan's) - however, some of your friends could use some assistance. Now you can help them out while also helping yourself. Anytime you refer a friend - and said friend purchases a pair of Sagan's - we'll give you a free trade. Just let us know whenever your friend purchases a pair of sunglasses, and we'll set you up with a free trade.
