While this isn't the best price we've seen for the LG G4, this offer from Virgin Mobile is certainly one of the best around at the time of writing. What makes this offer really good value is the inclusion of a free LG Watch urbane, which retails at £259. You can learn more about it by reading the LG Watch Urbane review on Wareable.
Reviews for the G4 have been largely positive so far, praising its screen, camera, battery life and overall performance, making it a worthy alternative to other flagship Android devices like the Samsung S6 or the HTC One M9. Be quick if you're interested though, as there is limited availability for this offer. Thanks to andy182 @ HUKD!
