The Android One Moto X4 is a good mid-range device, but the price was too high when it launched. It's only officially available from Project Fi in the United States, and the carrier has run multiple promotions in the past that brought down the price. Most recently, the phone dropped to $249 ($150 off).

Project Fi is now running another promotion on the Moto X4. If you buy two, you get $249 of service credit - essentially making the second phone free. That's not a bad deal at all, especially considering the X4 has Android 8.0 Oreo, a Snapdragon 630 processor, a 1080p LCD, and dual 12MP cameras.

The offer is valid until May 2, so you have an entire month to think it over. Here are the full terms and conditions:

One $249 service credit applies to an individual user on a Fi group plans who buys 2 Android One Moto X4 devices from to be activated by 2 users who are a part of a shared Project Fi group plan. One user must purchase both devices, and the credit will be applied to the purchaser’s account. Activation of both devices is required within 30 days of device shipment. This offer is valid from April 3, 2018, at 12:00 AM PDT–May 2, 2018 at 11:59 PM PDT, or while supplies last. Users must be active for 21 consecutive days to be eligible to receive credit. If one device is returned, the credit will not be distributed. This offer is only available for U.S. residents ages 18 and older with a Google Payments and Project Fi account. Limit is the smaller of 6 Android One Moto X4s or the size of the group plan. This offer can be combined with ongoing $150 off with activation discount on Android One Moto X4s purchased through Project Fi, and terms are subject to applicable laws. The offer is void where prohibited.
