Hey thanks all, I checked the manufacturer's site and they list them as an authorised dealer (well the main company, Geneva Golf LLC), and they have an ok return policy when compared to others on the net selling sunglasses (14 days no restocking, everyone else charges 10-20%)...the price was a cool $30 less than everyone else so I took a chance, worst case I dispute it with my CC should something go wrong.
Thanks again.
