PayPal now charges sellers a fee when buyers use a credit card.  
I just found this out when someone paid me for an eBay auction, with a credit card. PayPal told me I had to upgrade my account in order to get the money.  Nice incentive for me to upgrade, huh?
But they're still cheaper than eBay Payments and as a buyer you don't pay a fee.  I still like them.
