Nebraska Lottery officials presented a $50-thousand check to Dave and Theresa Gulizia on Friday.
They own the Speedy Mart of Highway 6 in Gretna where one of two $122 million Powerball Jackpot tickets was sold for Wednesday's drawing. The money is a seller bonus and is the top amount the Lottery distributes to a store that sells a jackpot winning ticket.
Nebraska Lottery director Jim Haynes says while they wait for the person who won to come forward, all eyes will be on the Mega Millions drawing tonight.
The top prize for tonight's 10:00 drawing has increased to $425 million due to heavy sales.
It is the fifth-largest jackpot in U.S. lottery history. Odds of winning are about 1 in 176 million.
