I actually debated getting this. No tax plus free shipping makes it a better deal than the $399 + tax from the MS Store the other week.
Then I looked up the list of XB1 game releases for 2014. And I decided I don't need to pay $425 for a paperweight. Most of the games I want are releasing in Q4 or in 2015. As good a deal as this may be, especially so soon after launch, I think I'll wait til Black Friday.
So bogus! I decided to go ahead and bite, but the $50 instant discount is no longer available! Now it's a $20 instant discount, which after the promo code brings the total to $459.98... Shoot, you can buy these for less than that elsewhere.
