It’s a situation that’s beneficial to all, more profit for the club, less empty seats, a return for SC holders, opportunities for non SC holders. I’d say it’s been a great success in a season of unparalleled demand. They also offer an easy way to transfer your tickets to other supporters (some clubs charge for this) which they obviously don’t benefit from, a lot of these tickets end up in the hands of potential new supporters/attendees. On top of this there are always tickets (at face value) on this forum, social media & supporters clubs, so plenty of avenues to get tickets
