6pm offers the RayBan Men's Aviator Sunglasses in Arista/Brown Gradient, model no. 0RB3454L, for $71.98 with free shipping. (They're available in Arista/Green for pennies more.) That's the lowest total price we could find by $63, although we saw them for $12 less in December. They have metal frames and feature 100% UV protection.
