^B & H and Adorama also have a terrible resale policy... if you returned a bad lens or camera a day or two after buying, they will repackage and sell to another poor soul.....
I learned this the hard way.... i purchased a 5D MKIII (was supposed to be new) but when i opened it, it had finger prints on the LCD and the eye piece looked like someone with a watery eyes or Pink eye was using it... luckily, i opened the box right outside the store, went back in and exchanged for a "New, New One".....
