Tickets for the 25th Anniversary Raw at the Barclays Center on January 22 will officially go on sale on Friday, but there is a pre-sale going on right now. You can use the pre-sale code “ISLES” (via the New York Islanders, who play at Barclays).
Tickets for the Manhattan Center part of Raw on the same day will also officially go on sale Friday and there will apparently be a pre-sale starting tomorrow morning at 10 AM ET, but no pre-sale code has been released yet. The Manhattan Center is a much smaller venue, so tickets will obviously go a lot faster there. Ticketmaster lists the prices for the Manhattan Center ranging from $78.00 – $803.00.
