I don't know of any but I do know that Lenscrafters (eyeglass store in malls) is related to sunglass hut and if you know anyone that works at one you can use their friends and family coupons there. My brother hasn't worked at Lenscrafters long enough to earn any coupons otherwise I'd send you one. I'm not sure how long you have to work there to earn them. Maybe a year??
