This is my first deal, so be nice! Amazon have Ken Livingstone's Memoirs on their Daily Deal (expires 23:59 Tuesday 29 November) at 92% off.
The book was released only a month ago, and the hardback copy has an RRP of £25. As it is 720 pages long, the Kindle version sounds preferable because of the weight alone!
Anyway, I'll be interested to see how this goes. I have no interest in buying it myself, and I'm sure it will split people on political issues, but I'd say objectively it's a good deal compared to its price everywhere else.
