Yep - same here. This person just tried the same story with me from an item I'm selling on craigslist.

"For my son's birthday"

Wanted to send me money in a hurry, just needed my paypal info.

Told her/him/Nicole that I needed security with Western Union instead.

They refused.

Be careful out there everyone!

Excellent!  These scammers are insistent that we send money to them via Western Union, but when we ask them to wire money to Us... ha!

Just tried to scam me on Craigslist.....

Same person just tried scamming me on my Craigslist post saying that he/ she is looking for a present for said son and wanted my PayPal account info and $100 shipping fee

I just got the same thing, on a camera lens I'm selling... researched their phone number, and saw this posting.  GREAT info... thank you !!!   I also referred the Scammer (Nicole) to this site...   LOL!!!

This is in the signature line, but only on first email;
  Nicole Rains Interior and Exterior Decorator Co.
  General Manager.
  You are blessed in Jesus name.

Here's our transaction emails, in order;

NICOLE: Do you still have it for sell? if so, what is the last price? and what is the present condition? get back to me as soon as possible so that we can move forward in this transaction.  Thanks.Nicole.

ME: Yes, $400, excellent. No phone number from you, no more replies from me. (no phone usually means a scammer)

NICOLE: Dear Seller, Thanks for your response. I was only looking to make this purchase for my son as birthday gift. I will offer you $400 Thanks, Nicole.

ME: Okay...  what's your phone number?
