 The cost to fight a giant grocery merger is going up. Washington now expects to pay up to $6 million to an outside firm handling the state's lawsuit against a proposed merger between Kroger and Albertsons. That's double the money previously authorized for the L.A.-based firm hired by the state attorney general's office. Colorado and the Federal Trade Commission have filed similar lawsuits. According to the Seattle Times, trials in all three cases are set to start in August or September.
