The National Lottery has revealed a €11.2m jackpot ticket was sold at the Texaco Service Station and Spar Express in Enniskerry, Co Wicklow.
The store on the Monastery Road sold the ticket for the biggest Lotto jackpot win in over two years.
The National Lottery is still encouraging players in Wicklow and surrounding areas to check their tickets.
The winning numbers on Wednesday evening were: 10, 13, 23, 24, 25, 44 and bonus number was 12.
Shop owner Ken O’Connor said: “We just can't believe it! We heard the news yesterday that the winning ticket was sold in Wicklow but we had no idea it was us until last night, it’s just fantastic.
"The shop is absolutely buzzing this morning and I am just thrilled for our customers and of course our staff.
"Just last year, we sold another winning Lotto ticket worth €5.7m at another one of our stores in Rathfarnham in Dublin so we’re definitely a lucky retailer for our customers.
"Whoever the winner is, we wish them every bit of luck enjoying this life-changing win,” he said.

A National Lottery spokesperson also confirmed it is still waiting to hear from the lucky winner.
They said: "It is possible that the winner is still unaware that they may be in possession of the winning ticket so we are encouraging anybody who has a ticket, to check it carefully and to contact our prize claims team on 01-836-4444 and we will make arrangements for you to collect your prize”.
The jackpot win was the 15th highest since the Lotto was launched in 1988.
But it was close to being shared, as a Laois player fell one number short - matching five numbers and the bonus ball.
