There was a huge ticket scramble this morning for the All-Ireland football semi-final between Mayo and Dublin.
Croke Park it set to have its biggest crowd of the year on Saturday with the showdown heading towards an 83,200 sell-out.
Tickets went on sale at 10am this morning with long queues forming outside both Centra and Supervalu stores.
Some supporters told of queueing for two hours for tickets, while others who tried to use the GAA's online official ticketing partner were met with virtual queues of up to 10,000 customers that lasted over an hour.
One fan tweeted: "At SuperValu in Lucan for nearly 2 hours to get tickets for the Dublin Mayo match."
There will also be a ticket allocation through various GAA clubs, but demand is set to outstrip supply for the highly-anticipated match.
A big rivalry has developed between the counties with Dublin going for a fifth successive All-Ireland titles and Mayo hoping to make their fifth final since 2012.
The other last four clash will see last year's finalists Tyrone take on Kerry at GAA HQ on Sunday.
