Here is a question I've been having. Why are designer sunglasses marked up so much more than the cheap sunglasses (in terms of percentage) like UV400? Most other apparels (jeans, sweaters, shoes) don't see this big of a discrepancy. A pair of UV400 is $10, a pair of Ray Bans is $100, and a pair of Gucci is $350. Where's all that money going in each case?
