North Carolina ? A store clerk’s slip-up at the cash register has paid off big time.

Wayburn Allen on Tuesday accidentally rang up two duplicate Powerball tickets for a customer in this western North Carolina town. At the end of the day, after she was unable to sell the second ticket, Allen paid for it herself.

The next day, Allen returned to the store and found the ticket matched all five numbers – earning her a $200,000 jackpot.

When Allen went to Raleigh to claim her prize, she met the customer who purchased the original ticket. The customer also will receive a $200,000 jackpot.
