Yes, that's basically the gist of it, though I don't know the details. FB is full of complaints about prices increasing substantially while in a queue for half of the day until the system was taken down.Have they been playing silly buggers trying to use some tech to increase prices for fans based on number of tickets sold, how busy the website is and other markers? Sounds like an effort to rip fans off. Pay more the same thing.
We were lucky and got tickets without being hit with increases (it seemed to affect GA and some grandstand tickets) but it's not an ethical way to treat customers.
