Check out sierratradingpost.com. Thay have a great selection of polarized fishing sunglasses, like Costa Del Mar, Kaenon, Native, Coyote, Maui Jim, and Action. I got a $120.00 pair of Costa Del Mars a few months ago for $59.00!! They came with 3 lens colors that you could interchange, and a nice hard case! Sign up for their e-mail list and you receive periodic coupons for 20% off or free shipping. I have bought all kinds of fishing gear from them.
