I have about 1/2 of our bills paid through BofA and the other 1/2 directly to the services themselves through their online services. Our mortgage payment always got screwed up with the BofA billing program for some reason, so now I just go into their website on the 1st and do it myself... same thing with Nextel, Verizon and a few others.
Verizon especially is famous for billing the WRONG amount - either over or under - usually over - and then shrugging their shoulders saying they can't imagine how it got screwed up. I don't care if it's 5 cents, 5 dollars or 50 dollars - I hate Verizon and don't want those bastards getting anything extra out of my account. lol
But yes - BofA is excellent for online bill pay. We also have a Washington Mutual account and I was less than satisfied with their version of the online bill pay program. BofA is MUCH better IMHO.
