Iphone 4 replacement glass price?

I dropped my iphone 4s and the back glass is all cracked and i wanted to know how much it would be to get it repalced! I only paid 90 bucks for the phone it self.

Go on ebay or amazon. The price varies

To do it yourself cost around $80 parts are on amazon "digitizer" for apple to fix it around $140

The cost of the back cover glass lens is about $10. But it's not easy to replace it. You'd better replace the whole back cover, which is about $13.
