as JFizDaWiz said, if you have a paypal business or premier account, you can get a paypal debit mastercard. It can be used to pay your bill.
I've had one for years I use it to pay for EVERYTHING. It gives 1.5% cash back, so I thats why I use it for everything. I get atound $100/month back. I think newer accounts only get 1% cash back, but hey its something.
