If you've got a Chromecast set up on your network, click this link right now and you should be eligible for $6 from Google just for owning a Chromecast. It's a Valentine's Day gift for your Google Play account. I will spend it on renting The Rock or something similarly unromantic.
And if you're not checking the Chromecast offers page more often, you probably should be, as we just learned when we pulled it up. We had five offers just chilling there, waiting to be redeemed. Free money. Who doesn't love free money? [Chromecast Offers via 9to5Google]
