Where can I sell an iPhone for cash?

I recently ended my contract with sprint and I want to sell my iPhone for at least $100. I won't do it unless I can at least get $100. I really don't want to sell it on craigslist and deal with sketchy people. I don't want to do gazell or any online thing mainly cuz I don't trust it. I want to do it in person like a store. I tried going to best buy and Walmart, but they would only give me $13-$30. Its in perfect condition, no scratches, no dings. It looks brand new. I have the charger and original box and it works perfectly.

Added (1). Its an iPhone 4S 8gb

Added (2). I tried selling it to a friend, but it is locked to sprints service and nobody wants it because its sprint. I hate sprint and everybody I know don't like sprint. I really don't get this whole locked thing

Added (3). the phones not stolen, I bought it from sprint, and I did a factory restore on the phone so it is like new.

Added (4). I also got a new phone from metro pcs

There's tons of posts on this but I don't know which ones are current enough/relevant.

There are so many people/companies selling non-OEM chargers online still so what gives? What's different about these versus what I've got? How do I know?
