Google is celebrating the Chromecast's second birthday with a free movie rental offer for owners. Whether you currently own a Chromecast, or are looking to purchase one, you have until December 31, 2015 to redeem the offer. Redeeming the offer is quite simple: You just need to head to open the Chromecast app, head to the settings and then redeem offers, or head to this link from your computer. From here you can search for a movie, courtesy of Google.

There are some limitations to this promotion, however. Unfortunately, Google does have a maximum of five redemption's per Google account. Depending how many other offers you have taken advantage of, you may, or may not, be able to participate in this one. If you don't already own a Chromecast, you can pick one up for yourself from the link below.
