Skimming Canada's deals, the Microsoft Store has the X1 bundle with AC: U and AC: BF for $350, and you get a free game of your choice. You also can save 25% off any of their black or fancy controllers. The free you get has to be among a select number, but the choices they give are good: Halo MCC, CoD AW, Sunset, GTA5, FH2, Destiny, Titanfall, but two weird choices.... AC: U again and Plants Zombies.
There is also that existing $100 trade in deal applicable to giving a working 360/PS3. But I'm not sure if they allow it on Black Friday, but I know the deal goes to the end of the year. They may do a black out period. Not sure. Better call them.
If they allow it and you have an old 360/PS3 to ditch, you can basically get an X1 for $250. If you don't care for those Ass Creed games, you can probably sell the codes for $50 total (maybe $40 for Unity and $10 for Black Flag). That brings it down to $200. You also get a free to choose from ($70). If you can swing all this and factoring tax you basically get an X1 for under $200.
$350 bundle + tax = $400
-$100 trade in 360 or PS3 = $300
-$50 sell Ass Creed codes = $250 out of pocket
but factor in getting a free $70 game and it's like you paid $180
