I was wrong. If you set up electronic bill pay with CCU there is a service charge of $3.95 to use it each month! That it a 10-15% addon to my bill! Here is what their website states:
Quick Pay provided by Billtrust
You can make a one-time payment without enrolling in eBill using your Visa card, Master Card, Discover card, checking or savings account. Billtrust charges a convenience fee of $3.95 to use this service.
Guess I will mail the bill or pay it online each month to avoid the extra charges.
