I don't know the person I am buying from?
 

Simple things to check when you buy items on a forum include;

>> how long has the person been a member?

>> have other people bought from this person?

>> is the person selling other items?

>> can I contact this person by other means? ie mobile number?

>> ask the seller for referances, other people that have had dealings with them.


If you are able to contact the person via a telephone it increases your ability to guage if the person is genuine. If they have not posted their number, simply send them a PM or Email asking for it. If they are not prepared to supply it, maybe this person isnt someone you want to buy through no matter how great the deal seems.
