I believe these still retail for over $400 USD when purchased without a 2 year contract. Here are completed listings of the same phone on eBay. they average between $300 and $400
Dude..Go on your local Craigslist. I just checked mine and 2 other states. 200 is the average but you can get it for as low as 150 pretty often.
Now, on the other hand, the iphone 5 goes for around 400 on local CL again...sure you didn't get your shit mixed up?
