Gayle Say, 65, of Coventry, England, said she bought some tickets for the Thunderball drawing and she called for her husband, Philip, when she discovered that one of her tickets matched all five numbers and the bonus ball in the Oct. 22 drawing.

"With the tickets in my hand, I rushed inside to tell Phil we had won and at the same time I realized another of the tickets had the same number line," Say told Birmingham Live. "I kept shouting 'we've won and we've won again.'" Say said the buying error was "the best mistake I ever made."
