Best Buy offers the Google Chromecast Streaming Media Player, model no. H2G2-42, for $30 with free shipping. That's tied with our mention from last week and the lowest total price we could find by $5. 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.
