Are your books brand new? How are they such good value?

All our books are brand new and delivered to us straight from the publisher. Our special sales editions are bought in bulk at a great discount - which we pass on to you!

Are the books different from what I've seen in the high street?

Special sales editions are made with more affordable materials, allowing the publisher to keep the cost price down, and we can sell it for less than the standard editions
