Paying auto insurance bills in full (twice a year) instead of opting for monthly payments - saves the monthly installment fee.
Also, having the right amount of income taxes withheld from my paycheck so I have either a very small amount to pay to IRS on tax day, or i get a very small refund. Ideal situation is to be almost even with tax liabilities versus credits. Why is this a savings? (So many people struggle with this concept..... Because if you deliberately have too much money taken out of your check thinking that your tax refund is a grand reward, you are letting the government borrow YOUR money for a year without interest! I do a much better job at putting the extra weekly money aside into an interest-bearing account, or into investment accounts. I realize that bank interest is low. But it's better than zero.
A consistent focused approach to saving is huge over time.
