Not sure if you can enter monthly or just once.

To get you started, sign up for your chance to win a £100 National Book Token every month by completing the form below!
You’ll be entered into a prize draw every month and the lucky winner will be notified.

I think this seems to imply that you might only need to enter once to be in all subsequent draws.
