Out of curiosity I just checked the website for Burnley ticket availability, as I have used the "re-sale" platform for this game. As expected, none of the re-sale tickets appear to be available yet (mine are in the Park End and none are available in there), and there appears to be quite a lot of other available seats, especially as Burnley haven't taken their full allocation (loads of available tickets in the Upper Bullens away section).
At this rate I can see a lot of the re-sale tickets either not being sold, or worst still, not even being made available. Hopefully ticket sales will pick up nearer the date of the fixture.
All I know is that with StubHub, by now I would have sold my tickets and some other fan would have picked up a nice cheap ticket or 2. I literally see no-way in which this new system benefits match-going fans. Yeah, there may be a few more "face value" tickets available for the derby, but I can see a lot of STH selling their season tickets for that fixture privately anyway. Just bizarre that EFC have changed everything based on a few complaints based on a single fixture.
