Visa credit card related question - and bags of course

  1. hello,
    just wondering if anyone purchased things without eBay and paid with their credit card via paypal. If things do go wrong with the transaction, like fake bag, are u still responsible for the purchase? Can u deny t he purchase or what should u tell ur VISA credit card company about it? I heard from other posts that they can deny the charges from paypal (cc) and then they will get back to the seller? Is that how it works? What sort of info do I need to provide my credit card company or paypal, since I didn't use eBay to make the purchase...thanx
