Free? How so?
In the state of Florida, windshield cracks and chips are repaired free of charge. According to Florida statute 627.7288, if you have comprehensive coverage on your vehicle your insurance company will pick up the tab for any repair or replacement that you may need. The law states that your deductible will be waived. In most cases, your insurance company will send someone to your home or office to replace or repair your windshield.
Same for South Carolina. Course my office has never had to replace a windshield due to bass lol
