How much does a used 16gb Iphone 4S cost?

An unlocked used Iphone with NO contract. Keep that in mind. I know it only costs $50 with a contract, but I'm buying it and connecting it through a government-funded program. It's my family members program.

Added (1). So IS $300 A GOOD DEAL? FOR ONE WITHOUT CONTRACT?

Added (2). RDMS: $150 for a NEW Iphone 4S? C'mon, now!

Between $320 and $440.

I was going to buy one for about £220 which is around $330 so yes that is a good deal

If it is a government funded program, the price of the phone is Way more than you should be spending on a phone. If they government is paying for it than get something cheap and basic

About $200 - 300 used, you can't use it on the Assurance program if that is your idea.

A new 16GB 4S only costs $100 (not including a contract). Even with a contract it shouldn't be more than $150, $200 at the most (for a new one).

If it's used, it should be MUCH cheaper than $300. Like I said, you could get a new one with a contract for less than that.
