DJI via Newegg offers its refurbished DJI Phantom 3 Advanced Quadcopter Drone with 2.7K HD Video Camera for $499 with free shipping. That's $40 below our January mention and the lowest price we've seen for this model. (It's $180 less than the best deal for a new unit today.) It features a 1.2-mile range, GPS-enabled geofence, intelligent battery, 3-axis gimbal, four pairs of propellers, and smartphone operation via the DJI Pilot app. Deal ends April 30.
