Ticket delivery to UK

It is not clear to me if you deliver to UK or not when booking through TCG. The details suggest yes "Search and book; make a payment; and then we will deliver to you". But the snswer to the question from Paul in the UK above suggests not. Please can you clarify.
Also do you discount the service charge if a number of tickets are being ordered (i.e. a number of journeys for a family of 4)
Thanks Dave from UK
