Oasis acknowledged in their statement that the roll out of tickets over the weekend had not gone as planned.
They said: "While prior meetings between promoters, Ticketmaster and the band's management resulted in a positive ticket sale strategy, which would be a fair experience for fans, including dynamic ticketing to help keep general ticket prices down as well as reduce touting, the execution of the plan failed to meet expectations.

I'd love to see an explanation from whoever put that quote out how they envisioned dynamic pricing would keep ticket prices down. It's entirely optional to fix a ticket price, there isn't an outside influence forcing their hand.
