In Priceless, bestselling author William Poundstone reveals the hidden psychology of value and explores how we react to the most pervasive persuader of all: price. Charting the burgeoning growth of price-consultants who advise retailers from Nike to Nokia, Poundstone shows how behavioural decision theory has revolutionised the pricing strategies of major corporations.


Informed by fascinating behavioural experiments and packed with real-life examples, Priceless explains why prices are so important, and the tricks that companies use to sell their goods. It will prove indispensable to


anyone who buys, sells, or negotiates.
