I had experieince with the BoA round up thing and I thought it was a good deal. But then again, when at the gas station I started making sure I didn't go over the next dollar when I was close to filling up....so you do kind of adapt to it one way or another.
I just moved over to WaMu. Completely free checking with all the amenities and their online Savings paying at 5% APR. Can't beat it baby.
Oh, one thing that I did love about BoA. They just started this thing where you can actually kind of balance your account on line by checking off transactions as they occur. Not useful to all, but it helped me to make sure I was keeping track of everything and that there weren't any strange charges I didn't recognize.
