CoastalContacts.com again offers a free pair of glasses via code FREEGLASSESUSA, plus around $13 for shipping for new customers. That's tied with our mention from last month as the best offer we've seen from them. Note that this will end after it is redeemed 10,000 times, so act fast. Shipping also includes a mandatory insurance fee which may vary depending on the frames you choose. Sales tax is charged in most states for Coastal Contacts Lenses.
