They offered an additional game with the bundle.  Basically $60 in extra value. 

You get to pick 1 extra game you want, to go with it.

It was behinde the PS4 until this deal happend, then climbed up the ranks.

This makes me almost sure both Slims will be 249$ when black friday comes.

I recall making a thread (which got locked) suggesting people wait to buy an XB1s because MS will need to offer some insane deals in order to try and keep up with Sony ...

Oh I see, they need bundles like those on Europe because they are dead over here and would be good to see them selling again at decent levels like the 360.

Wait, you can get a $165 CE free with the XB1? Either a mistake on Amazon's part or Microsoft has gone full desperate mode.

You can also get an XB1 for less than $300 at Target. Get a XB1 + $170 Rock Band bundle for $299 (Rock Band bundle for free), return the Rock Band bundle (trade in value $108.51), final price = $191.48.

I'll personally be shocked if XB1 doesn't win NPD this month.

The fact that Recore hasn't exactly set the world on fire and MS would like for it to do well, I'm leaning towards the latter. Right now it looks great on the Amazon charts but MS are now devaluing their console even further than they have in the past and this is the new SLIM to boot.

As far as your edit goes, it's the 26th and Sony have had 3 consoles ahead of XB1 consoles for the greater majority of the month. I'm not sure a last minute surge can put them ahead but it will certainly close the gap. I could be wrong but I still think it's likely going to go to the PS4.

Still think Sony takes it.

But this should help Xbox close the gap abit.

At the cost of them makeing profits. Great for the consumer that wanted a xbox though.

Full desperate Microsoft is always the best Microsoft, they know they are dead WW so better try hard on the US.

Xbox one

TBH due to the Target thing I think this might be the month where Amazon might be wrong.
