Apple doesnt offer a menu or repair services except for replacing the battery.
Apples out of warranty or not covered under the warranty repair price pays for an exchange.

This 3rd party repair company charges $100 to replace the glass only - if the LCD is not damaged.
If the LCD is damaged also, they charge $200, which is the same as Apples repair price that pays for an exchange.
