I have also fallen prey to this company. I sent a pair of the larger style wayfarers in, due to the left arm never really being installed right.
Now they no longer make them, and I for that 50% off offer, it I do the legwork and find a price and color code. I just e-mailed them back to ask for the return of my glasses. What do you think the chances are that I'll get them?
If no return, I'd have to go along with their offer, or I'm the one that's out! So much for American customer service and company relations. No wonder we're usually on the phone with Rawalpindi, Peshawar, or other places...
