Please add your items to your cart, and when you reach checkout you can choose to pay by card or PayPal or request an invoice to be sent to your school for payment before goods are shipped. Packs and DVDs are + VAT, books have no VAT. Please note that we can no longer sell our products to customers in EU countries because of the high costs of customs duties and fees following Brexit. This is a matter of great regret for us (as of 23 December 2021). We also no longer sell to South Africa.
