No one has yet come forward to claim the half a million euro prize, after the winning Daily Millions Plus ticket in last Thursday's draw was sold in Ballyhaunis.
The lucky Quick Pick ticket was sold on Thursday at Caulfield's store on Main Street, and is worth €500,000 after winning the 2pm Daily Millions draw.
Earlier this month, a Co Roscommon player scooped the same prize in the draw on 8th March and collected his winning last week.
Shop owner Seamus Caulfield says they're thrilled that one of their customers in Ballyhaunis is half a million richer.
The National Lottery is urging players to check their tickets, and the lucky ticketholder should sign the back of the ticket and contact the National Lottery Prize Claims team at 01 - 8364444.
