@boomerang,
Most of the time I pay my bills (gas, electricity, water, council rates, etc) at the local post office. (this is in Oz. Others' payment options may be different.)
A very convenient service. One stop/pay most bills.
But on the odd occasion ( eg the dentist, or annual accreditation with my professional association, or RACV subscription ) I usually pay by cheque, through the post.
I
never use my credit card online to pay any bills.
