Update: the price is now back to $1,996.95.
The Nikon D750 camera is currently selling for $1,696.95 at Amazon (shipped from and sold by amazon.com). This is $300 off compared to the $1,996.95 price of the D750 at B&H and Adorama. Note that this is a "regular" D750 that comes with US warranty and not a grey market or refurbished model. The listing is either a mistake or a new price drop that will become official next week.
