A Biloxi woman won $20,000 on a Mega Millions ticket purchased from Winn Dixie #1513 in D’Iberville for the Aug. 8 drawing. She quick picked her numbers and always purchases the multiplier. She matched 4 out of 5 white balls plus the Mega Ball, yielding an initial win of $10,000. Because she purchased the Megaplier (which was 2 that night) option, she doubled her win to $20,000.
