If you're one of the few people in the US who wants a Chromecast for your living room and doesn't yet have one, you might want to check out this Best Buy sale. The already inexpensive dongle has been reduced to $29.99 ($5 off), and it comes with $20 of free Google Play Store credit. Assuming you'll eventually spend twenty bones on the Play Store (and I should hope any regular AP reader would), the effective price is a cool ten bucks.
For a limited time, Google is giving out $35 in Play Store credit to anyone in the US who buys both a Nexus 7 and a Chromecast. If there are enough things you want from the Play Store to spend $35 bucks on, then this deal is similar to buying a Nexus 7 with a bunch of content and getting a Chromecast tossed in for free.
This offer is valid with any Nexus 7, so don't let that deter you from filling up that shopping cart.
Google would love for you to put a Nexus 7 under someone's tree this holiday season, but they also don't want anyone who can't part with $229+ at the moment to feel left out - so they're now offering customers who purchase a Chromecast from Google Play with a free HD movie rental. If Play Movies isn't quite your cup of tea, you're also free to take $6 in Play Store credit instead.
Update: Google has updated its Play gift card support page to reflect this change, and this change hints that at some point this feature might allow you to gift Play Store credit:
Thinking about picking up a Nexus 7? You might want to get on that before the end of this month (right here), as the $25 Play Store credit promotion Google announced with its slate at Google I/O expires on September 30th. That means you must redeem the promotion before that date by signing into your Nexus 7 with a Google Wallet-linked Google account (that has a credit or debit card on file).
