This is misinformation, Glass companies charge more to insurance so they can waive deductibles and compete by charging the customer less, effectively ripping off the Insurance companies. This practice is illegal in some states, and is not done by Safelite.
Safelite charges the same or less to Insurance companies, and does not participate in deductible lowering price wars, which are currently popular in the California market with other glass comapnies.
XYG glass is actually the company that makes the original equipment glass on many Ford and GM cars, and actually costs more than Safelite's Windshields - made in their USA plant.
