In my time working as a bank manager, I saw the company make a fortune on overdraft and other fees. In fact, that was our second biggest income source after loan interest. We loved profits from fees, but there is one secret that the banks don't tell you: how to get a fee refund.
We have been told that we need to balance our checkbooks for decades. This common advice is given with the best intentions. We are told that by tracking our transactions, we are protecting ourselves from overdrafts and ensuring nothing unauthorized happens in our accounts. That is true, but there are better ways to do all of that.
