In total how much would an iPhone 5C cost? (plus a case)?

I'm looking into an iPhone 5C. But i need to know an estimate or exact cost of the iPhone 5c?(plus a case) thanks!
:)

Unlocked (without contract) iphone 5cs cost about $550 before tax. So with a good case the total can be about $630. On contract, Best Buy is selling the phone for free with a 2 year contract.

Probably around $220 including the case and a one year contract
