One great scam about paypal.....

Let's say I bought a Shimano reel off ebay thru paypal. I have one already exactly the same, butsmashed and broken to pieces. I send my paypal payment in, receive my new Shimano reel. I can issue a "stop payment" thru paypal, and say I received and smashed on broken reel...in which I would send back to you.

Long story short, I get a new reel for free...and you get my smashed and broken reel for nothing in return. Paypal can really suck in situations like this.
