Anyone still in search of last-minute tickets to see Coldplay at Croke Park tonight should be prepared to pay - with tickets now soaring as high as €575.
Standing tickets available on the Seatwave website are going for €475.
Seats as far back as the Davin Stand are priced at a hefty €575.
Seatwave is a Ticketmaster company and prices are set by third parties selling tickets on the site.
Many fans were left disappointed last year when the tickets originally went on sale.
They were immediately faced with prices as high as €700, with tickets being sold for inflated prices on re-seller sites.
Now with the concert so close, a couple looking to see the band - fronted by Chris Martin - could be set back a whopping €1,358 for two of the in-demand tickets, including booking fees.
More than 82,000 fans are set to descend on Croke Park for tonight's hotly anticipated gig.
It's not just GAA headquarters that is in for a busy Saturday, with a massive night also in store in the capital for those looking to continue the party after the gig.
Stadium director Peter McKenna said Coldplay's Head Full of Dreams show tonight and U2's upcoming gig later in the month are set to make €80m for the local economy.
Security will be heightened for the event, with 1,000 security guards and up to 200 gardai present tonight.
The Garda Armed Support Unit (ASU) will also patrol the concert in the wake of the recent terrorist attacks in Britain.
Insp Tony Gallagher, of Mountjoy Garda Station, confirmed to the Herald earlier this week that members of ASU will be in attendance.
He said that although the security threat in Ireland remains moderate, armed gardai would be present at "all of these events".
As with recent concerts, backpacks will not be allowed and fans are being advised to arrive early for security checks, and to use public transport where possible.
Event controller Eamonn Fox said that they have always had "very tight security" in place, but they have increased it in the wake of recent events.
"The additional bag search is something we had done before on the pitch areas, and now we've increased it to the seating area, so it has heightened our awareness," he said.
