Tomorrow only (1/28) starting at 9am EST through 12pm EST, Coastal Contacts is giving away 10,000 more free pairs of glasses! They've done this several times in the past and I haven't heard any complaints. You will have to pay shipping and handling, but that averages about $10-15. Be sure to double check that the pair you want is eligible!
Just "like" them on Facebook and then click on the "10K America" tab to get your code!
