I noticed they removed this "funding" option a while back. Lot's of folks opting to have the card issuer reverse charges.
The work around is to insist your seller send an invoice. Then the option to pay with a card reappears. You still have to look for it though, they don't make it an easy one.
Oh, and eBay/Paypal sucks.
I just bought a photograph yesterday and paid via PayPal funded by my credit card. It’s still there, but you have to select your funding choice each time.
They don’t make it easy, but you can pay with credit card funding.
