PIP = Personal Injury Protection, nothing to do with physical damage to vehicles.
Leslie, usually shops end up having to replace the whole windsheild when they may only want to re-seal the window. It usually cracks or breaks when they take it out. Depending on the car may cost $300 - $500, depends on the car etc.. Make sure it is not just the moldings on the outside that need to be replaced like Rice Rocket said, that is different.
