A Lotto player is set to miss out on half a million euro if they don't claim their prize today.
The National Lottery is still searching for the winner of the Euromillions Plus top prize from Friday 24th February.
The winner has 90 days to claim their prize - meaning today is their last chance to the collect the money.
Spokesperson Sarah Ruane is making one final appeal.
'The winning ticket was purchased on Thursday the 23rd of February at Dunne's Stores in Tallaght County Dublin.
It was the day before the draw whcih took place on Friday the 24th of February and again it was the euromillions plus top prize worth five hundred thousand euro, so the Dublin winner has just today left.'
