When Google launched the Pixel 3 and Pixel 3 XL for $799 and $899, respectively, the tech giant also reduced the price of its previous-generation Pixel 2 XL. During the time when the new devices were officially unveiled, the Pixel 2 XL was discounted to $699 while the Pixel 2 remained unchanged at $649. Instead of continuing to sell the two models, Google outright discontinued them, but that might also mean the company is getting ready to introduce new products in the near future.

If you visit the Google Store right now and attempt to access the Pixel 2 listing, you will be directed to the Pixel 3 page instead. If you visit the ‘Phones’ section of the website, you will notice the terms Pixel 3, Stand, Buds, and their related accessories, but no mention of the Pixel 2 or the larger Pixel 2 XL.
