I have one available (VERIZON). Used it for only 2 weeks (got it as a replacement from square trade so very likely refurbished though). Comes with an unbelievable transferable warranty from square trade (goes until August 2015, only $25 deductible per claim, still 2 claims remaining, next day delivery, if you make a claim and they don't have the phone in stock, they will give you the amount it will cost you to buy a no contract, brand new phone which will continue the warranty).
Asking $350. Located in 5towns but I work in Queens and will be going to Brooklyn this coming Sunday.
I also have an almost Brand New white verizon S3 (bought it "unlocked" but couldn't get it to work with Airvoice Wireless/AT&T). Asking $300
Also have a used S3 (VERIZON. Blue. Asking $200
I'll throw in an extra (used) battery or two (or 3) for each phone as well as a battery wall charger
