You will see a little * on your quote that says "[your car] may have advanced safety systems that require recalibration after glass replacement to keep you safe. Additional costs may apply."
They normally charge $500 - $700 extra for that, and they won't give you that full estimate UNTIL you are at the shop getting the $350 window installed.
If you call them out on it they will say "we cant give an accurate recalibration cost until we have your car".
Also.. if you sit on a quote from them for about a week they will normally send you out a $100 of coupon (if you don't have any type of ADAS system, its worth waiting to get that coupon)
