The other day I received an e-mail from Amazon. Hoping they might happily inform me about the fact that one of my books has cracked the top 1000 in some category or other, I actually opened the message instead of deleting it immediately.
Of course it was just another of those recommendations they pester you with. You know what I mean, right? Things like: Since you bought 'Give The Anarchist A Cigarette' by Mick Farren, you might also be interested in this here book by Allen Carr.
