Viagogo's top price for a ticket to one of the two Radiohead gigs at The O2 Arena or the gig at the Manchester Arena in October is £600 plus shipping, VAT a ticket guarantee and a £180 booking fee.
The site is also enforcing a minimum purchase of two tickets at once.
Upon announcing the UK dates, the group said that it would implement a paperless ticketing system, limit the number of tickets per transaction, disallow name changes after purchase and make photo ID a requirement upon entry to the shows in a bid to clamp down on secondary ticketing.
The band's managers Chris Hufford and Bryce Edge called secondary ticketing "wrong on so many levels" at the beginning of the month and announced a partnership with Ticket Trust to allow fans to buy and sell tickets at face value plus a handling fee capped at 10%.
The practices of secondary ticketing companies such as Viagogo have been a hot point of discussion since they were exposed in a Channel 4 Dispatches documentary at the end of February.
