‘"We’ve seen sales of Flutie Flakes double since Sunday’s game," said Stefanie Zakowicz, corporate spokeswoman for Tops Markets. "It’s too early to say it indicates a strong trend, but sales are way up this week." And the sales spike isn’t just a Bills-country phenomenon. Pittsburgh-based PLB Sports, the company that created the private-label cereal and sells it to retailers and on its Web site, has charted a 40 percent uptick in orders from around the United States for Flutie Flakes and other Flutie products.’
