Couldn't find this deal on here so thought I'd add it.
Many deals for Chromecast are around $25-$35.
Why not pay the same $35 for the Chromecast but in addition get 1 month of Youtube TV.
Youtube TV offers live streaming of many networks like ABC, NBC, etc.. One month is $35. After one month payment you will get complimentary Google Chromecast free of charge.
