Who else loves the Kindle Daily Deals? I'm signed up to the daily email alert.
There's some random and not so great stuff but you can pick up so many really good books for just 99p.
I'd say I buy 2 a week on average just because it's such an accessible price. Eg yesterday I got the Agatha Christie classic And Then There Were None.
Plus as they're electronic no worries about cluttering up the lounge and they just sit there in a virtual queue waiting to be read whenever you want.
I don't work for Amazon before someone accuses me of that I just think it's a great scheme and I read more than I would were I buying paperbacks that I'd have to find space for and at £7.99 a go.
