The woman said she went into the store and bought her mother's Powerball ticket, along with a $2,000,000 Colossal Cash scratch-off for herself.
The two women next went to the car wash and, while waiting by the vacuums, the woman's boyfriend called and asked her to get him a Powerball ticket, too.
The player said she decided to scratch off her $10 ticket in case she won enough money to cover the cost of her boyfriend's ticket, and discovered she had won a $2 million jackpot.
She said winning the top prize was "unbelievable."
"I wasn't feeling lucky," she said. "I wasn't having a great day, and I ended up winning the lottery."
The winner said the first thing she did with her winnings was pay off her house and she is now considering taking a vacation.
