To buy just use the link opposite/above, which will take you to the Stripe payment gateway. All payments are secure and I don't have access to your card details. The book is priced at £13.95, which is a bit of a piss-take, but that does include postage to anywhere in the UK.
If you want a book posted outside of the UK then do get in touch and I'll quote you postage at cost.
Books are signed by the author (me), drop me an email if you don't want it signed or would like a specific message.
