Verizon mistakenly shows a 256GB variant for both the Google Pixel and Google Pixel XL
In the chart, you will see that there is a listing for a 256GB Pixel and a 256GB Pixel XL, along with prices for both. But before you work yourself into a lather, running over to your local Verizon store with the idea of trading in your Motorola DROID Turbo 2, take a breath. Confirmed by Verizon reps, there is no 256GB version of the Pixel or the Pixel XL here now, or on the way.
What happened here is that some one at Verizon simply copied the same trade-in chart that was posted for the Apple iPhone 7 or Apple iPhone 7 Plus since both of those models offer a 256GB variant. You can still take advantage of this deal to pick up a 32GB or 128GB Pixel or Pixel XL. Keep in mind that if you order the 128GB Google Pixel XL, the phone won't ship until March 3rd.
