The same thing happened to me. A Lizzy Jacobs had been trying to buy a computer from me from KSL.com in UT. I've got some of the same emails (word for word). I finally got USPS money orders in the mail. Two for $950. (less than half the ammount of the item). We took them to the Post office and surprise, surprise, they are fake. Once the evelope was delivered I got a ton of emails with addresses to western union part of that money to someone else. Also got a call from someone who sounded like an older asian woman wanting to know about their payment. Right about this same time I got a friend request from this person on facebook. Really?! Lame.
This is the email they've been using:
[email protected]. I googled it and they had a blog with posts saying some of these same things word by word. That has since been taken down.
