When I called iCracked about the same thing, they (very honestly) told me iPhone 5 screens are uber expensive and they currently cost more than it would to get a replacement iPhone 5 from Apple, which is currently $229. The way the markets work though, iCracked said they will be swapping those screens out at half the price pretty soon. I'm assuming it's the in-cell technology in the new screens that makes them so expensive.
