Eyeing a Chromecast? If $35 is too rich for your blood, Google has a new promotion that could land you one of the dongles for free.

Anyone who uses Android Pay at least 10 times between now and Feb. 29 will get a $35 credit you can use toward a new Chromecast.

If you don't make it to 10, don't worryyou might not be able to get a Chromecast, but you will still get a few fun little perks for your participation. After your first Android Pay-based payment, Google will toss you a free song from Google Play Music. You'll get a second free song after your second payment, but you'll have to wait until your sixth payment to rack up a third free song. After that, you'll get nothing else until you hit payment number 10, when it's Chromecast time.

According to Droid Life, you might not see the promotion in your Android Pay app just yet. Don't start making payments until you do, or it's possible that they might not count for the promotion.

"According to a reader who sent us the info, the Android Pay Rewards is showing up as a card in your list of cards that when tapped, brings up the UI you can see in the screenshots below with details on the promotion," reads Droid Life's report.

Since the promotion is tied to Android Pay, those using iPhones and iPads are out of luck. (Here's hoping you have an old Android device or, if you're desperate, access to a spouse or relative's Android phone.)

Also, before you think that you can just head over to your local supermarket and quick-pay for like, 10 boxes of Tic-Tacs in a row, know that each Android Pay tap has to occur at least five minutes after the previous one for it to count for the promotion. So, you're welcome to be as cheap as you want to get your Chromecast, but you're going to have to hang out at the store of your choice for almost an hour. We recommend just spending money as you normally doyou have more than a month, after all, to earn your Chromecast($29.98 at Walmart).
