I managed to grab a couple in the end. It’s amazing how few tickets have come up for a game that’s not against one of the so-called bigger teams. I have been parked on that ticket page most of the week and the 2 I bought were pretty much the only 2 together I saw!
It has happened to me more than once that I have put a pair on there and only one sold, even though there were plenty of single tickets available. I’m guessing the buyer wanted an empty seat next to them and there is nothing when you list them to say only sell as a pair.
