How much is a iphone at Sprint?

If I pay up front, will it turn out to be like 400 bucks? I had tried that at Walmart's Cellphone store thing and it was 400+31 bucks up front without a deposit.

With this promotion, the iPhone 5c will cost $0 for a 16GB model and $99 for a 32GB model. The iPhone 5s will come out to $99 for 16GB, $199 for 32GB, and $299 for 64GB. The iPhone 4s, like the 16GB iPhone 5c, will be free of charge. Of course, this promotion means you have to sign a contract with Sprint.
