If I buy a iphone 5 case can i use it for the iphone 5c?

I'm buying an iphone 5c and I google if the iphone 5 was the same size and shape as the iphone 5 so i could probably buy an iphone 5 case for the iphone 5c and it said it was the same shape and size.

No.

They are different sizes and the case will not fit.

No id say they are different. But i know what you mean like the iPhone 4 and 4s they both have the same shape and cases a fit both perfect but i think the iphone 5c has a new shape and design. I recently both a case for my iphone 5 from www.howtoidevice.com and they have very reasonable prices, they do cases for all iPhone and iPads.

No, they are not interchangeable. The iPhone 5c has a rounded back, and the iPhone 5 is flat.
