Ladies and gentlemen, if you don't have a Chromecast at the moment and are even remotely interested in owning and using one today is your lucky day.
Best Buy has it discounted to $29.99 (from the usual $35) and on top of that they're throwing in $20 of Play Store credit. (You'll receive the promo code via an email from Best Buy, which is how they do these things. I got my Netflix promo codes the same way when I first picked up tons of Chromecast when they came out.)
You can pick up the Chromecast and see the promotion for yourself here. Who knows how long this is going to last, so pick one up as soon as you can.
For what it's worth I'm planning another Chromecast related post for this week or next week. Mostly cause of the interest from that "worst gadget you've bought" article on the main page the other day. (Apparently it is only the "worst gadget you've bought" to some people. Most find it awesome!) That and with the functionality rolled out over the past month or so to the Chromecast app and support from various other apps and developers things have gotten better and better for Chromecast owners as of late.
