Non-existent customer service was looking for a pair of shades, and noticed this site was cheaper than all the rest, which was my first flag. Never do business with a website that doesn't give out their business address. And their phone number is a MagicJack # that nobody picks up. I used my best knowledge to stay away from here.

* never again ZBESTGLASSES SOULD BE CALLED ZWORSTGLASSES. I placed an order with ZBESTGLASSES.COM and received the wrong item. I've contacted them twice asking them for authorization to send back the wrong item and receive what I ordered. I paid extra for 3 day UPS, but it took 10 days for me to receive the WRONG glasses. I have filed a grievance with my credit card regarding this purchase. I am a professional buyer, and by far, this is the ZWORST company I have ever dealt with. I had to give them "1" on the rating, whereas I would given them a minus 10.

Got my Costa's from here I did my research on the reviews. Take note that no reviews say anything bad about the sunglasses. It took 2 weeks for mine to arrive, but they are definitely the real thing. I too started to worry and even reached out but didn't receive a response. A day later I got an email saying they had shipped and even got a tracking number. If you are patient and will wait 2 weeks, it's worth the wait. I saved $80 on mine. I'd buy again. My Costa Conch 580g's are awesome.
