You think those headlines come cheap? Rupert Murdoch’s New York Post is raising its newsstand price a quarter, just like it did a year ago, meaning the splashy tabloid will now run you $1 on weekdays, beginning Monday. Saturday editions will cost $1.25 and Sunday copies are going up to $1.50. When the Post jumped from 25 cents to 50 cents in 2006, the rival Daily News dropped their price and grabbed some readers, so if they’re ever going to reignite the largely dormant tabloid war, now’s a great time.
