Well I too have fallen under the scam by the Nigerians!
My initial email from the buyer said he was living in the US but currently on a church conference in Brazil. He claimed the item was for his son who is studying at a University in Lagos, Nigeria and he wanted me to send it as a gift. I got the spoof emails from Paypal and as it was my first international sale I didnt hesitate when sending the goods and the tracking number - especially as looked so real!
Now I have lost an Ipod worth £200...money I was relying on for Christmas! Wish I had read about this scam a long time ago so would not have been taken in by this!
