That’s exactly happened when a ticket error occurred for the British Summer Time Festival at Hyde Park in London.
According to IBtimes, a link meant only for employees of the event organizers were leaked allowing fans to purchase tickets regularly priced at approximately $117 for under $5.
Once discovered, most fans were afraid that the error would be corrected and the ticket purchases would be cancelled, but that wasn’t the case. AEG Live has confirmed that all discounted tickets will be honored for the festival.
