If your looking to purchase something from "out there", using paypal is simple and secure if done correctly for both, have the seller send a invoice from their paypal to your paypal to you using only your email address that paypal has on file from you, pay the invoice and have the buyer ship with tracking, important for both paypal and you(if you dont receive it or it gets lost)paypal stands behind this to make the seller accountable this way if you need to open a dispute
