Celebrations are under way in Duleek, Co Meath as Lowthe's Londis has been named as the shop which sold the winning ticket for Wednesday's €8,915,056 Lotto jackpot win.
The owner of the ticket is yet to come forward to claim their prize, the National Lottery said.
The winning normal play ticket was sold on Saturday 1 of October.
Store owner Seamus Lowthe said it is "complete magic" to learn that his family's store was involved in the win.
"The first thing I did was check my own ticket as I did the Lotto on Wednesday night for the first time in a while.
"I was in complete shock when the local rep called me the following day to let me know we'd sold the winning ticket.
"We’re a local family run store, open 38 years and selling the Lotto 30 years and this is our first ever big win. It’s complete magic for us."
Mr Lowthe said the town and surrounding area will be abuzz with news of the win.
"It's going to create some buzz and atmosphere around the village over the next couple of days.
"Everyone will be wondering who won. I hope it’s someone local, it would be great. It’s a class amount, life-changing.
"I’m absolutely delighted for the winner and I’m delighted for us. We wish them all the very best."
The Meath player is the eighth Lotto jackpot winner of 2022 following wins by players in Wexford, Mayo, Meath, Dublin (2), Kilkenny and Galway, the National Lottery confirmed.
They are also the 30th National Lottery millionaire of 2022.
