I use em, but mostly because they were the first to take me on 10+ years ago. I'm ambivalent about them.
While LA has a lot of credit unions, my ADHD brain doesn't want to figure out if I can use ATMs across the vastness of this area, so I just stick with it.
Don't they require that you hang onto the receipts and turn em in at specific times of the month or something? Because that doesn't jibe with my stupid brain.
