If you act fast you can pick up the Fire HD 8 Android tablet for only $79.99 (for the 8GB model, and $99 for the 16GB model). That's $70 off the price of this five-month-old tablet, making this price one of the better deals so far this year.
And by fast I mean that these sales usually last 6 or 7 hours before the price goes back up.
In related news, Amazon is also offering a $50 discount when you buy a pair of Fire Kids Edition tablets. Those tablets come with a two-year warranty, a (worthless) case, and one-year subscriptions to Amazon Freetime Unlimited, all for a cost of $150.
If you need two tablets, that is honestly the better deal than $80 for the Fire HD 8. But YMMV.
