Costco offers its members the Yamaha 7.2-Channel Network AV Receiver, model no. TRS-7790BL, for $439.99 with free shipping. (Non-members pay $24.50 more.) That's $360 less than the best deal we could find for the identical RX-V779BL model. (Costco has a unique model number for this receiver.)
It features 95 watts per channel RMS, 4k Ultra HD upscaling, Bluetooth, WiFi with AirPlay support, Burr-Brown DACs, and six HDMI inputs. Deal ends December 5.
