MADISON, Wis. (AP) — Wisconsin lottery officials say a winning Powerball ticket worth $1 million is days away from expiring.

The ticket was purchased Aug. 6 at Aberg Avenue Mobil on Madison's east side. The location is also known as Kelley's Market. The ticket matched the first five numbers, but missed the Powerball.

Winning ticket holders have 180 days to claim their prize. The person who bought the winning ticket has 11 days left to claim the prize at Wisconsin Lottery headquarters in Madison. If not, the winnings are used for property tax relief.

The retailer who sold the ticket still receives 2 percent of the winning ticket amount up to $100,000.
