GAA fans keen to support the boys in blue stocked up on Dublin jerseys ahead of Saturday's crucial quarter final.
Ahead of their team's victory against Louth last Saturday, Dublin supporters flocked to sports stores throughout the capital, with some shops reporting a noticeable increase in sales.
Ciaran Hulsman, deputy manager of Champion Sports' Jervis St branch, said the store was surprised at the demand for GAA jerseys in recent weeks.
"On Saturday, there was quite of lot of fans coming in to buy jerseys -- there were actually a lot more people than we expected," he said.
"We re-stock all the time, but we've sold so many over the past few weeks that we are really running low now. There was a big increase in the number of people coming in on Saturday, probably twice the normal amount."
And now they are bracing themselves for a further surge as proud fans gear up for a heated weekend at Croke Park against Tyrone come kickoff at 4.00pm right after the Down v Kerry showdown (2.00pm).
"As long as [they] keep in the finals, I expect jerseys and GAA merchandise to be very in demand," Mr Hulsman added. "I'd say every day now as long as we're in, we'll see a lot more people coming in to buy Dublin jerseys."
And while they come in nearly every shape and size, retailers have noted that adult male jerseys sell the best - but sales of women's items are expected to increase as the week goes on.
"In this particular store, we would sell more adult jerseys - at least ten every day in the past few weeks, if not more."
Hill 16 are hoping that the Brogan brothers return to form especially Alan (pictured) who was way off target against the Wee County last weekend.
The normally clinical forward managed to bag just three points from the tally of 2-14 as Pat Gilroy's men cruised to victory over a disappointing Louth.
Alan is also hoping to rewrite history and banish the memories of 2008 when he went off injured against Tyrone (in the quarters) and watched from the sidelines as the Dubs crumbled.
