Not a member currently, but think I may well be next season, as the Supporter's club has a ticket offer on today for membership: If you buy a half time draw ticket and don't win, you just have to send the ticket to the supporters club and you get a quid off supporter's club membership next season- essentially you get the half time draw ticket free.
Full details at:
