I've had one for a couple of years and they have never charged me anything for paying on line.

My Chase and Citibank cards don't charge if you pay several days in advance.

If the payment must be posted that day in order to avoid a late charge then they charge a 'service' charge.

I pay almost of my bills online. The one exception is the power co. Progress Energy wants to charge me $4 for the privilege of using online payments.(I want a paper bill )
I mail that bill.

When I had Sprint, they wanted to charge a fee for paying in the office. One of the many reasons I don't have Sprint anymore.

I’ve never had Chase or Citibank charge me anything for paying on line. For anyone that charges for the ‘privilege’ or don’t have the option, I use my bank’s bill pay service.
