You don't have to. When you go to GS, make sure the CM understands what you want to do (i.e. price bridge). Ask them if they know how to do it. Have your numbers figured out ahead of time so that if the CM's numbers don't match, you can point it out and fix it before they do anything. If they disagree, ask for a supervisor. If you still can't get satisfaction, go to another GS. I still recommend outside MK. They haven't let me down yet, even though I have had to clarify #'s with CM. I've never had any of them refuse to price bridge once they were clear on the procedure.
