Coastal (also known as Coastal Contacts) takes 25% off all glasses via coupon code "PRESIDENTS" as part of its Presidents' Day Sale. Even better, it yields free shipping on all orders. Plus, receive an extra 25% off all lens upgrades automatically. That's the best discount we've seen from Coastal in several months, although we saw 50% off all glasses last fall. Several terms and conditions apply. Deal ends February 18.

Note that a mandatory shipping insurance fee, that varies based on the value of the frames, will also be added.
