That is correct. They have changed the default and they actively discourage you from using your cc. I believe that they want you to establish an account with them, have the funds, and play the float. I just ignore their warnings about paying interest, and switch the account, and use the cc.
Beware of PayPal
I made a payment via PayPal and just noticed that they took the money out of my checking account instead of my credit card. They made this change without notifying me! Worst thing is that there's absolutely no way to contact them. They don't respond to my emails and they have no phone number to call! This is horrible!
