I'm trying to sell a lovely display unit and only replies I've had have been from scammers. I've forwarded both to Trade-It who immediately blocked them. E-mails to watch out for are from Jim Hike, [firstname.lastname@example.org] and John Lucas, email@example.com].
Always look for bad english, not putting their name on first e-mail, wanting to use PayPal and not being able to get to see the item.
One guy who tried to scam me when I was selling my car offered me £200 more than I was asking and even sent me an e-mail supposedly from PayPal saying that he was genuine and had insurance. Shame his spelling and english was so bad!! That immediately got forwarded to PayPal as well.
Be vigilant everyone
