The British boy band are touring the UK and Europe next year and demand is high as it is the first time in 15 years that they have toured with singer Robbie Williams.
Tickets for the Progress tour went on sale at 9am on October 29 and websites crashed as fans desperately tried to get their hands on some tickets.
However people were soon cashing in on the demand and within hours tickets started appearing on the auction site with bids reaching £560 for a pair of tickets for a Birmingham show.
The band recently held a press conference to announce the dates of the new tour.
