The robber will end up getting far more than $390 out of this after litigation.
I don't know if I could ever comfortable trust a Craigslist transaction. My friend got some deal on a X box and he didn't want to go to the homeboy part of town by himself. So I went along with him. Some homeboy selling stolen X boxes. Before we pulled up, he had just sold some drugs to some other homeboy.
I live in the DC area and use Craigslist all the time (buy and sell). Funny story, I had a 2007 Vizio 40" TV I wanted to sell (it was an early model "flat screen") so I listed it for $125 (I way under priced it). I got a shit load of emails on it...I had to go to work so my wife said she'd sell it. She said some guy with an email "smokeycraig@" emailed and wanted to come over immediately to get it. So she emailed him back (I had already left for work and she didn't consult w/ me). She said some big black dude pulls up, walks INSIDE the house, handed her the money, picked it up and left. It was middle of the day, so she said she wasn't too concerned. I wasn't happy w/ her about it!! Smokey-fuckin-Craig! WTF?!?!
Anyhow, I just sold a wood stove that I bought and used for 3 years off of CL (for $500) and sold it for $600. I have a vacation/second home (a cabin in the Shenandoah's) and I bought a ton of stuff for the cabin off of CL.
In DC, if I see something I like at the store I'll usually check CL first. There's 6+ million people within a 45 minute drive.
