Paypal is for the buyer ... the seller can get screwed !!
Example of something I've seen a few times. Buyer gets the parts and figures out it wont work for what he wants. He files a claim with paypal saying it wasnt what he was told or it has a small scratch. He wins everytime, gets his money back and your out the money and fee's ... oh yea your also out your parts.
I almost refuse to use paypal not because the stuff isnt good .. but because there is a lot of scumbags out there !
