Coastal.com is offering a free pair of glasses to first time customers. Read the fine print and browse through the frames you can get free. There were hundreds for me to choose from, and I liked so many of them it was hard to choose just one! Enter code FIRSTPAIRFREE at checkout to receive the discount.
You do have to pay shipping and required shipping insurance. My total was $14.85, which is a steal compared to the last time I purchased a pair!
