Best Buy via eBay offers the Google Chromecast Streaming Media Player for $29.99 with free shipping. (Amazon offers it to Prime members for the same price.) That's the lowest total price we could find by $5, although we saw it for $5 less three weeks ago. 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. It also allows you to use your Apple or Android device as a remote.
