As one of its daily deals, Best Buy via eBay offers the refurbished Google Chromecast Streaming Media Player, model no. H2G2-42, for $20 plus $3.99 for shipping. That's the lowest total price we could find by $8, although we saw a refurb for $4 less in December. It attaches to your HDTV's HDMI port and connects to your wireless network to receive streaming online video, music, websites, and more from your smartphone, tablet, or laptop. Deal ends today.

A 90-day warranty applies, although it's not clear who provides it.
