Groupon, the popular discount retailer, is selling the original Chromecast for just $20. The units that are being sold are refurbished by the manufacturer, but if you have been on the fence or want to grab an extra for travel, this is a great deal. This is the original one rather than the newest ones that Google just announced, but that doesn't mean that it still isn't worth purchasing.

For those not familiar, the Chromecast is an HDMI streaming media player that allows you to display pictures, videos and more from your phone to a large display. The original price was $35, but you can save 43 percent now and pick one up for just $20. If you are on the fence about whether or not this is an accessory for you, be sure to check out our full review.
