Update: Sometimes these deals end as soon as we can get a post up. The refurbished Chromecasts are now showing up as out of stock.
I know the Chromecast isn't exactly what we would call an expensive gadget, but I like to save money wherever I can, and since you clicked on this headline, I can see that you like to too. So here's what you came here to know. Groupon is currently offering refurbished Chromecasts for just $25 to anyone living in the continental US. That's $10 bucks off the usual price.
But I hear what you're saying. You didn't come here to save $10. You came here to save $20. So to get the price of the Chromecast down to just $15, enter either 10FORU or HAPPY10 at checkout.
The deal will last for ten days or until supplies run out. Some purchases require careful thought and consideration, but this price point is well within the impulse buy range. Who cares if you already have two Chromecasts and only one TV when it's only $15? Set it aside somewhere and save it for Christmas. Just don't try to stock up on too many at once. Only one coupon code can be applied at a time, and they both take $10 off the entire order, not each unit.
