Online at Coastal.com A coworker told me about it a while back; and after a recent eye exam I went online, chose a fresh pair, entered my Rx, and WON! I only paid for a lense upgrade. $160 pair of glasses for $30. I used my vision insurance to cover a pair at the doctor's office and my part came out to be $165. So, just putting it out there to those that may be interested.
