Best Buy via eBay offers the open-box Onkyo 5.1-Channel Home Theater Receiver, model no. TX-SR353, for $149.99 with free shipping. That's $8 under last week's mention of a new one in a sealed package and the lowest price we've seen for this receiver in any condition. (It's $50 under the best price we could find for a new unit today.) It features 140 watts per channel, 4K UHD passthrough, Bluetooth, and four HDMI inputs.
Note: This item is new but may not ship in original packaging.
