For a limited time, Google Fi is offering the Google Pixel 3 and Pixel 3 XL for $300 off. That’s a better discount than the one Amazon offered during Prime Day, when the phones were available for $260 off.

Google Fi’s discount brings the 64GB and 128GB versions of the Pixel 3 down to $499 and $599, respectively. The discount also brings the Pixel 3 XL with 64GB and 128GB down to $599 and  $699, respectively.

To be eligible, you must be a new or existing Google Fi customer. You must also activate the Pixel 3 or Pixel 3 XL on Google Fi within 30 days of you receiving a shipment confirmation email. If you don’t activate Google Fi within 30 days of receiving the aforementioned email, you’ll get charged the discounted amount.

The good news is you don’t have to maintain the Fi service after activation. That means you can buy the phone, activate it on Fi, receive the phone, and cancel the service. Best of all, the Pixel 3 and Pixel 3 XL available through Google Fi work just fine on all four major U.S. carriers.

If you missed out on Prime Day and have been eyeing something more powerful than the Pixel 3a, you can grab this deal at the link below.
