GAA fans are still having difficulty getting their hands on tickets for this weekend's sold-out All Ireland semi-final between Dublin and Mayo.
Some tickets are appearing for resale at three times the market value despite extra tickets being made available yesterday.
Dublin are set to take on Mayo in front of an 82,300 strong sell out crowd at Croke Park this Saturday.
Extra tickets went on sale at the GAA ticket office on Dorset Street yesterday morning but were sold out within 2 hours. By lunchtime yesterday the tickets were sold out at SuperValu and Centra stores and on tickets.ie.
The day before many supporters were left disappointed after they unexpectedly lost their place in an online queue.
Now, opportunistic touts are cashing in on the demand with some tickets are being offered for sale for up to 150 euro online.
Last month the government agreed on new legislation to tackle ticket touting.
Anybody caught trying to upsell tickets can be brought to court under these new laws.
