It wasn't that ago when I has figured out how to mix/max overdraft checking because I was so damn broke. I'd over draw my account by $980, the overdraft fee was $20, and my account would be -$1000. Then 29 days later, I'd get a cash advance on my credit card, pay bring the checking account up to $0, and then make a payment to the credit card company for $980. I was slowly digging myself deeper into a hole just so I could hang onto having a bank account.
