hey everyone i have a few questions. Im looking to buy a set of wheels off a guy from out of state, he is gonna be shipping them to me. My question is ive never used paypal..how does it work? i mean i get the concept, but does it charge? im just worried about sending the money, but never getting my wheels. I dont think the guy would do that, but gotta play it safe. Whats my best option for sending money to someone? That if i didnt get my product, i could get my money back?

thanks for any help/info!!
