B&H is having a special one-day sale on the 12.9-inch iPad Pro that Apple released in late 2018. The normally $1,299 model, which has 256GB of storage and has both built-in Wi-Fi and LTE connectivity, is down to $849 -- it's the cheapest that this iPad Pro has ever been.
Of course, this is not Apple's newest 12.9-inch iPad Pro, which has a significantly better camera system and a faster (A12Z Bionic) processor. However, this 3rd-generation iPad Pro that's currently on sale still has most of the same features, such as Face ID, support for Apple Pencil and it basically has the exact same display.
For the exact differences between the 12.9-inch iPad Pro (2019) and 12.9-inch iPad Pro (2018), check out the comparison page on Apple's website.
