You want to report the Best Buy Credit Card you went to pay your bill on line and because you didn't pay within two days on line you were charged 15.00 Now other cards you can pay the same day on line?

You should read the user agreement when you applied for the credit card. It would have told you, you must pay within two days before the due date.

Many credit cards have different online payment guidelines. American Express allows you to pay your bill the same day, but for Capital One you must pay before 3PM EST for the payment to be accepted that day.
