Staples offers the Google Chromecast Streaming Media Player, model no. GA3A00028A14, for $20. Plus, Staples Rewards members bag free shipping. (Not a member? It's free to join.) That's tied with our September mention (which required pickup) and the lowest total price we could find by $7. 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 January 2.
