I've done that with the past few transactions I've conducted. Of course those who were dealing with me knew I was LEO and a regular on the boards and have a spotless iTrader rating. I've had some on here that wanted to buy and they had serious red flags like no post, no info on them and they requested info that didn't pertain to the item I was selling, also asking if they could have someone come inspect the part before they made good on the payment. I don't think so, homey don't play that!
Never grow up, it's a trap!
