1day have the latest Chromecast (video, not audio) available today for $70 plus $5 shipping, available at https://www.1-day.co.nz/products/google-chromecast-2-black
Not bad a price, given Pricespy shows next best price at $99 (http://pricespy.co.nz/product.php?p=3341551).
A pity they don't have the audio available as well...
