Better together pair sale

Some things are better together, but we've made these books even better again by taking 25% off their price when bought as a pair!

Add both to your your online basket and the discount will be applied at checkout. But place your order by 28 August, because this special price ends then—unless stock runs out first!

(If you don't have the same number of copies of each book in the pair in your order, the standard quantity discounts will apply instead.)
