At this time, for UK deliveries, our system only supports UK billing addresses. 

We are aware that this is an inconvenience to some of our customers, and we are working very hard to implement a solution in the near future to enable international billing addresses.

In the meantime, you can work around this by purchasing National Book Tokens (independent gift cards accepted by many booksellers across the UK) and redeeming them on with a UK billing address.

You may also wish to contact your favourite independent UK bookshop directly, as some may be happy to process international orders in their own way.
