The name associated with the number is Cinthia Parker probally false. For all you newbee's to selling stuff, I have probally had over 20 different scammers doing the same thing in one month of placing the add.
I was scammed out of 400 for a video camera sale on Ebay. I had clearance to ship it, Paypal claims I didn't. Then the guy's check bounced and he never sent camera back. This wasn't even the Western Union style scam and it still happens occasionally even with Ebay. Also with 200 bucks worth of bedding that, after I sent the money, the person decided to go bankrupt. Lost that too. All Ebay would do is suggest I leave bad feedback.
Well, whoop de doooooo! Unfortunately 800 bucks is under a grand and it's not "Grand Larceny" so it's hard to get any help from law enforcement. But the FBI would probably, at least, log the case.
I know it doesn't help, but don't feel stupid. It happens everywhere.
