Harman Audio offers its factory-refurbished Harman Kardon 665-watt 7.1-Channel 3D-Ready Home Theater Receiver, model no. AVR 2650, for $399.99. Coupon code "275AVR2650" cuts that to $275. With free shipping, that's $325 under the lowest total price we could find for a new one, although we saw a refurb for $76 less last summer. Features include 95 watts RMS per channel into seven channels, Ethernet, Dolby and DTS audio decoding, and 3D-ready video switching with five HDMI 1.4a inputs and one HDMI 1.4a output. A 1-year Harman warranty applies. Deal ends May 3.
