"If you purchase tickets through Ticketmaster and can't attend, you'll have the option to resell your tickets to other fans at the original price paid on Ticketmaster's Face Value Exchange. Please note, tickets to these events are mobile only and restricted from transfer."
I was reading this that you should only buy tickets from Ticketmaster…..but maybe that's incorrect. I did see some tix available on other resale platforms but don't know if I should trust that they will be valid.
