Well, the 100$ Check Coupon is for real.
Called them yesterday afternoon and spoke to Gibson. They do a conference call with you and your insurance company to verify coverage and that they will accept what insurance pays. Then with insurance off the line they set up today as the install day...you can either wait for them to call you or call them after 830 to get your window of time for the appointment. Gibson said I was 9-11, 30 minutes later Victor called and said he'd be here in 30-45 minutes...he was. Installation took 30 minutes, clean job, got check, very friendly installer.
Yah I recommend them.
