Best Buy via eBay offers the open-box Pioneer Elite 7.2-Channel 4K HDR Compatible A/V Home Theater Receiver, model no. VSX-LX102, for $278.99 with free shipping. That's $21 below our mention of a unit in retail packaging from three weeks ago and the lowest price we've seen for it in any condition. (It's also $51 under the best deal we could find for a sealed unit today, excluding the below mention.) It features 4K and 3D pass-through, Dolby Atmos and DTS:X decoders, an AM/FM tuner with 40 station presets, WiFi, Bluetooth, built-in Chromecast, four HDMI inputs, USB, and remote control.
