Aside from diamonds or a trip to Hawaii, a book token is the best present anyone could ever get me, so when I heard about Book Aid International's Reverse Book Token scheme, I was intrigued. You simply donate £10 to the charity, and you get a voucher to send to your friend or family member letting them know that 8 books (bargain!) have been sent to people in the developing world on their behalf.
If you're interested, email tokens@bookaid.org to request a voucher and once it arrives, make a donation. If you want to make a more regular commitment join the Reverse Book Club which involves giving £5 every month. (Slogan: "4 books for £5 - and you never receive a single one of them!")
