Members of the group, who take turns buying a ticket each week, didn't realize they won.
"One day at work, a few of us saw an article about a winning Lotto 47 ticket that was sold in Ortonville and remembered we had never checked our ticket," an anonymous group member told Michigan Lottery officials. "We texted the club member who had purchased it asking where she purchased the ticket and if she had checked it yet. When we got a reply from her saying she had not checked it, but purchased it at Tom's Market, we knew right away. We started jumping and shouting with joy!"
The ticket matched the winning numbers for the June 18 drawing: 02-04-06-17-31-36.
The Lunch Bunch Crew elected to take their prize in a lump-sum payment of about $1.2 million.
"We are still in shock," a club member said. "Winning is life changing for all of us."
