Yet again no match for the multitude of pre-Christmas sales, but $284.05 looks to be the best price on a 1TB Xbox One at the moment (unless your local Aldi still has stock gathering dust in the cabinet). It includes Fallout 4 and Fallout 3 Download Tokens as well, so that's about $20 worth of fun there. If you go through CashRewards you'll get another couple of dollars back as well.
Yes, it's the old fat model, so no 4K or HDR either - but at least it has a dedicated Kinect port. Unfortunately the $60 off $300 spend AMEX promo has already ended, else it would have brought it down to being a great deal. That being said it's still significantly under the price of any of the Xbox One S 1TB bundles at the moment though.
these things are pretty cheap these days
