Now that Google seems to have some Pixel XLs back in stock on the Google Store, it's running a limited-time promotion to hand out a free case with each purchase. If you go to buy a Pixel XL, you can just add one of Google's silicone cases in a variety of colors to your cart and see a $35 discount applied automatically. There's no specific end date on the deal, as it's simply listed "while supplies last" — but as we know, that may not be long when it comes to the Pixel XL.
The deal is only available for the Pixel XL, and only for the $35 silicone case — which is interesting, because it could easily get away with letting people pick up the cheaper $30 hard plastic case for free instead. But either way, we can't look this gift horse in the mouth. Perhaps the knowledge that the Pixel XL is in stock and you're getting a free case will be enough for people to buy,
