I'm trying to sell my iPhone?

I noticed on eBay the prices are a little more than what I can sell it for on Craigslist. It's a little scratched on the metal on the side but the screen has a cover and is not scratched at all. On Craigslist I'm also getting bugged by resellers offering me around 350. I called apple and asked if they can replace it cause it has apple care but I don't have the apple care plus. Any suggestions

Sell it on ebay for a cheap price and get a new phone on contract.
