B&H has the Canon 6D for $1649 (reg. $1899) with free shipping and 4% rewards. This is a new item, not refurbished. The deal also includes a free Canon camera bag, SanDisk 16GB SDHC memory card, Oben monopod and spare battery.
I have no idea how long this deal will last. You need to add the 6D to your cart to see the deal. Check it out here at B&H Photo.
