Good luck to your transaction ( be careful ), always remember that some people on this website are greedy specially when money is the main character. Other option, you can get bitcoin on some exchanges just to prevent some dirty works of others.
I don't think people are greedy!
Its just that PayPal payments are reversible which makes it a high risk to the person receiving the funds
