I was selling a psp with a buy it now for £180 and also got asked to post to nigeria for her son who she loved dearly!!!!!!!! Again i recieved emil from 'paypal' asking me to give them a post tracking number and then they would send my money to my account!!
I phoned paypal who confirmed that these emails were infact spoof!
Please allways double check if you have any worries over an item.
