Will the housing of the Iphone 5c be for sale?

I got the back of my white iphone 5c scratched. That is the polycarbonate plastic which was was scratched. I was wondering if they will be selling this and how much will it probably cost?

You will have to look it up on eBay or google.com.

I don't believe Apple sells parts but you can contact them and see what are your options as well:
