Amazon has decided to surprise us today. They've put the second-gen Kindle Fire on sale
in the US and the UK (everywhere?), offering it at a $30, £30, and €30 discount from the regular retail.
Note that this is not the Kindle Fire HD but the slightly less capable Kindle Fire with a lower resolution screen and weaker specs. While I wouldn't usually recommend this model when it was only $40 less than the KFHD, I would say that today it represents a much better deal.
I've found the Kindle Fire on sale on all 3 of the Amazon websites I've checked.
