Meant to post this on Monday, but all week The Times have been giving away a free Penguin (Celebration Range) book with each issue (usual cover price of 70p).
Thursday's free book: The Shadow of the Sun by Ryszard Kapuscinski
Friday's free book: The Beach
The books RRP is £7.99.
So far I have only seen the promotional editions within London, and in WHSmith, Tesco's or Sainsbury's.
