One thing I've yet to clarify is whether when you use your credit card via Paypal do you get credit card company protection on the purchase as normal. I'm sure I read somewhere that you do not because Paypal's transaction is simply to take money from your CC and only then pay for the item for you, eg your credit card isn't used to buy the item and thus you have no recourse to your cc company if anything goes wrong with the purchase...

CAVEAT EMPTOR!
