The couple, who are not from Clare, bought their winning €7.50 Quick Pick ticket while “passing through” the County.
The ticket, which was the 40th jackpot ticket to be purchased in Clare, was bought at O’Keeffe’s Spar, known locally as Roslevan Stores, in Roslevan, near Ennis.
The lucky couple, who do not wish their win to be a public one, declared themselves ‘delighted but not surprised’ to have won.
The lucky husband told Newstalk: “I always said I’d win Lotto, but it was still a very big surprise when it happened, and all the more because I’ve been playing since 1988, when the game began, and always play my own numbers”.
“On Wednesday, I included just one line of Quick Pick numbers – as insurance – and that’s the line that won”, he added.
Clare has enjoyed an unprecedented run of luck over the past two years in particular with seven lottery win’s being scooped in the county since since 2008.

In March 2014, a €24 mix play winning ticket scooped a massive €8,302,204 prize for another lucky winner in Kilrush.
