6pm takes 11% to 77% off select men's, women's, and kids' sunglasses, with prices starting at $9.99. With free shipping, that's tied with last month's mention and among the best discounts we've seen on sunglasses from 6pm this year. Choose from brands such as Oakley, Tommy Hilfiger, Calvin Klein, and Vera Wang. Deal ends October 2.

A best bet is the Calvin Klein Women's CWR649S Sunglasses in Black Fade (pictured) for $47.99 with free shipping. That's the lowest total price we could find by $7. They feature integrated nose guards and a protective case included.
