Nothing amazing, and not as good as deals in the US, but the Last Hunt has some sunglasses added to their site. They are each shown at 25% off and also have free shipping right now. If you wait, they often have sales such as 10% off >$100, 15% off >$150 and 20% off >$200. Could be better than free shipping if you are getting a more expensive or multiple pairs.
