PayPal really, really wants payment from your bank account rather than a credit card. In fact, to buy from many individual sellers they insist on it. The reason for this is clearly because CC companies can reverse the payment if you claim fraud... and PP sometimes does not protect you very well from fraud (and some claim, acts so because it can then freeze accounts and pocket the balances).
So... \"caveat emptor\" and don\'t let too much $$ sit in your PayPal account in case it magically gets frozen for \"fraud\". You wouldn\'t ever see that money again. But since it\'s the only way to buy off eBay you really have no choice but to open an account.
