You get a low ball perice on lien, they do the bait and switch and if you don't fall for it, your order is out of stock for 6 weeks.
I ordered a Nikor lens. I got an email to call for verificaiton. When I called, they we going to do me a favor by giving me a 'better' sigma lens for the same price. When I goggled the Sigma lens, it was actually $100 cheaper. I asked for the Nikor lens (wouldn't you). When I called 2 weeks later, the Nikor conveniently was out of stock. That is how they protect them selves.
STAY AWAY
