If I was in Vegas I be spending more time playing the machines than answering my Emails from fifty people wanting photo's of a silver strike that I may not have the camera to do it with. If you pay by PayPal it is a credit card that you can stop payment if it is a sham through your bank. It's easy and I've done it, but Paypal won't help you at all because they want their money from both sides so they only help the seller collect. So use your own bank because they are own your side, and they will go against Ebay for bad charges against Paypal. It will take a couple of months, but all will work out in your favor. Trust me I've had to go through it with Paypal.
