Was Teresa Giudice cooking the books at a book signing in New Jersey this week? Video footage obtained by RadarOnline indicates that Giudice, who recently pled guilty to several fraud charges, insisted on a "cash only, no receipts" policy while autographing her latest book at an event Wednesday night, asking $25 in cold, hard smackers above the $110-per-person admission price. "When you walked up to her, the woman next to her was quick to advise that it was $25 and 'cash only,'" an eyewitness says. "It was the hot topic of the event. Why would someone insist on cash only?"
