Oakley Vault cuts up to 50% off select men's and women's sunglasses and replacement lenses, with prices starting at $19.99. (Prices are as marked on the product page.) That ties our mention from last week as the second-best discount we've seen on sunglasses from Oakley this year. (We saw up to 55% off in May.) Shipping starts at $3.91, but orders of $50 or more qualify for free shipping.
