I was just about to make the same comment when I saw yours. I moved our business accounts to a local credit union and realized substantial savings in our financial costs of doing business.
Credit unions are owned by their customers, and enjoy a NON-profit status.
Banks are FOR-profit corporations, and they pass their tax burden to customers, but they pass their profits to shareholders who often bank elsewhere, instead of customers.
As usual, investopedia explains credit unions well.
