My experience is that they make offers, such as "money back guaranty, 364 day warranty," and then evade following them by small print, delays. In my case, they finally agreed I could return the glasses, I did, and they never issued a refund. I'm out $96.

Hello Claudia,
We're sorry to hear that you encountered difficulties with our discount coupons while placing your order. There are limitations to our discount coupons but most orders are eligible for discounts. The only order that will not be eligible for a discount is if the frame is already on sale and the lens selection is the value package which already included in the cost of the frame.
