Somebody offering me too much on eBay, seems like scam?

I'm selling my working water damaged iPhone 5 on eBay, started it at 370, which I thought was kinda high. I just received a message from an eBay user. They asked if they can pay me 670 for the phone, I don't get it. Why would somebody want to pay so much more. It seems suspicious. How do I figure out if this is a legit buyer.

Added (1). Well I don't understand how I would sell it to him for 670 when the auction has it at 370. Do I end the auction and tell him to pay me thru PayPal? I was always used to bidders winning an auction, then paying right there on eBay. Is there a specific way I should tell him to pay me? I've just never had someone send me a message and offer more (way more) than the asking price

Added (2). I think I'll just leave it alone, since new iPhone go for the same price. Seems fishy

Sprint: iPhone 4S to iPhone 5?

Why are iPhones more data efficent?

My buddy has a iphone 4s I have a samsung galaxy s3. We both have Verizon. He streams movies all day and I use Facebook for 2 hours and we use the same amount of data in that time span. Is there something I can do with my Android device to be more data efficient, or is Android just data hungry?

Apple chargers stop working?

We have lots of apple products in my house which leads to a lot of chargers but for some reason they all seem to be crashing or breaking and no one can charge the products. I have an iPhone 4s and my charger has been working fine since the day I got it (almost 2 years ago) now for some reason if i plug it in, it doesn't start charging. I have to unplug it and plug it in again to start charging. There's no tear or rip in the plug and i'm concerned because i'm going away in a week and i don't want to buy a new charger if I don't have to. Could your charger stop working?

Iphone 5 bought in the US, could I replace it?

Iphone purchased in Feb. 2013. The phone is not at all damaged on the outside. But problems occurred during an upgrade (as notified on the phone) and now I can't turn it on. Only the white apple symbol remains on screen.
I have the case it came with and my receipt. Could I ask for a replacement in any apple store in US?
Would I have to pay extra?

NO! I'm 15 and my iphone is my life, please help me out and put yourself in my shoes for just a sec, i've searched how to connect it to my computer but its not working, i'm in a recovery screen at the moment, when i re-turn it on, it goes back to recovery, and when i hook it up to my computer, my computer says " usb device not recognized" and i take it out put it back it like 15 times, and same message, it connects occasionally, really rarely, but i was thinking maybe there's a program i can download or there's a handy tip i can use to make my computer recognize my phone, there's nothing wrong with the cable, nor my computer, its my phone, i've connect a ipod up perfectly, just my frigin phone.
