Yep, had quite a few lately. Most are easy to spot but they are getting better at making them look legit.
I have had a lot of emails which are what I call the "Nigerian Scam", it goes a bit like this: "Hello, I am an oceanographer stationed at sea, or a Minister of a Church, and would like to buy your (insert product for sale) and also pay the shipping, if you could just reimburse my shipping agent with a Western Union payment of (inset dollar amount, usually around $900-1000), as I am unable to make payment to him directly" and that is the last you will see of your money.
The payment will show in your Paypal account as a "pending payment" and the moment they have your $900-1000, the payment is withdrawn.
I have never been caught, but know of a couple of people who have. If they manage to scam only one person per week, that allows them to live like a king in Nigeria!
