It looks as though no one has mentioned this, yet.
Amazon is offering Kindle Fire tablets for $49.99 "and up."
I'll let
Amazon's website do the rest of the talking.
CORRECTION & ADDENDA: The email message that I received, about this offer, said that the Fire 7 is "starting at $49.99;" the comparison chart on
the webpage that I cited above says "starting at" $49.99. However, the banner ad, on
the aforementioned webpage, shows
$39.99 for the Fire 7, with the $49.99 price marked through.
(If you cannot get the order page to show
$39.99, I recommend that you call customer service at Amazon and
insist on them honoring the price that they have on the webpage. I had to do that on an item the other day. After hem-hawing around for about 20 minutes, the representative finally offered me a credit. I took it--to me it was like cash, since I spend money at Amazon (usually for ebooks

) all of the time.)
Other Fire tablets are temporarily marked down, also, including Kids Tablets.
The webpage indicates that this is not a permanent reduction in price, but a "limited-time offer."
