In case anyone hasn't noticed, Waterstone's who are advertising this book at the highly competitive price of £16-30, are now offering a furth 5% discount until the end of May.

The advert keeps appearing on this site, but basically you will just need to enter the promo code HL5486 when pre-ordering. Well, 82p is 82p when all's said and done. Buy a third of a pint that will mate.
