I sent mine in for a cracked lens, they said frame was damaged too. So yes, about $100. Then at the BASSMASTER fest at Rayburn, they had a booth and offered free repairs/cleaning. I handed him my glasses that I had replaced only a few months earlier, and the guy starts cleaning and says, we'll replace the frame for free. He just did it and the frames were practically new. I didn't get it.
They have lifetime frame warranty. The first time you sent them in you didn't get charged anything for the frame replacement, that's just how much the lenses cost.
