This deal has ended.
Overstock has almost 20 pairs of Diesel sunglasses with many at only $49.99, despite all having retail prices over $100. Plus, use this 7% off coupon (there is also an 8% off coupon for new customers) which drops $49.99 to $46.49. As always, shipping is only $2.95 and there is no sales tax (except UT, IN). Of note: Ralph Lauren sunglasses are also very well-priced.
