ONLY credit card via paypal ..ie cc has to be primary way you pay on paypal after 45days the cc plug is only way to get refund... (don't make my mistake wire xfer what I did with BFL)
Just make sure you understand the consequences of doing this. You are telling your credit card company that PayPal didn't perform when they did all, and only, what you asked them to do. This can seriously damage your relationship with PayPal. You could wind up joining me in the PayPal Lifetime Ban club. (We have cookies, so at least there's that.)

if it has been more then 45 days in my case paypal "told me" I could go thru the cc company..but alas I did not do it thru cc option on paypal so was moot
so if you are after the 45 days you may be ok (not sure but from what was told by paypal rep on my options)
