The deal comes from Amazon subsidiary Woot, where it is priced at $439.99 for a brand new 64GB model. If you opt for the more capacious 128GB version, you're looking at $489. There are two strings attached to this deal, one of which might rule it out as an option for you if you're a Verizon or Sprint customer. This is the international version of the Pixel 3 XL (G013C), which means that it is GSM-only. That limits you to carriers like AT&T, T-Mobile, and they're MVNOs in the United States.
The second string, which shouldn't be too much of a hindrance, is that the only color available is Not Pink. If the hue is not to your liking, you could always slip it into a case, which is probably a good idea for an expensive smartphone in the first place.
The Pixel 3 XL might not have all the fancy modern tech like the Qualcomm Snapdragon 855 SoC and Face Unlock of the Pixel 4/Pixel 4 XL, but is still at incredible smartphone -- especially at this price. The Pixel 3 XL has a Snapdragon 845 SoC, 4GB of RAM, and a 6.3-inch 2960x1440 OLED display. It also has dual 8MP selfie cameras and a fabulous 12.2MP rear shooter backed by the Pixel Visual Core.
