Was it an OEM windshield though? I'm not doubting the price difference, but when I needed one replaced on another car I owned, SafeLite also initially offered me a replacement (with sensors and whatnot) for about 60% of the price of an OEM one. Luckily, in my state insurance is required to cover damage to windshields (though I did have to pay the price difference between the aftermarket and OEM part).
