The lotto ticket holder has won the guaranteed first prize in Lucky Lotteries Mega Jackpot draw 1316, Friday, May 17.

The winning ticket was sold at Donges Supa IGA.

"We're very excited to have sold the first prize in the Mega Jackpot," Wendy Donges said.

"We need to reassure if anyone does come to claim the prize that they'll be treated with privacy and discretion."

It's the second major prize sold from Donges Supa IGA after it sold the $10,000 second prize in the $2 jackpot earlier this year.

The lotto franchise opened at Donges IGA in August last year.
