Yea its a scam,Ive had the same kind of replys when ive been selling stuff,When ever i think its a scam i reply saying something like ive got so many things for sale can you remind me what advert you saw,If its for real they will get back to you.
The thing that gives it away is when he is saying: if you don't have PayPal account yet, it is very easy to set up, go to
www.paypal.com and get it set up, after you have set it up i will only need the e-mail address you use for registration with PayPal so as to put the money through. I have a pick up agent that will come and pick i after i have made the payments.I hope to read back from you soon.
Also if i think its a scam i will say where are you from because i can travel to you,When ive said things like that ive never got anything back.
