Consumer surplus is the difference between the price that a consumer is willing to pay and the actual price paid. In this case, the half-price sale decreased the actual price paid, leading to an increase in consumer surplus. By buying more books than originally planned, the consumer may have paid more in total, but the discount on each individual book increased their overall value and satisfaction, leading to a higher consumer surplus.
