I had a couple of sessions of refreshing repeatedly for an hour or so, with no joy - kept missing out. New options pop in to the list every so often and then it's a mad rush to select the seat (found best available worked better) and get it in your basket. Must be 200-500 people sat doing the same thing. Had pretty much given up but still had the tab open this morning, refreshed once and a LS ticket popped up. It's like buying hyped clothing/footwear from a few years ago.
