What smart spending habits have saved you the most money?

[Nora.L]

I'm trying to develop better smart spending habits, but I'm not sure where to focus my efforts. What smart spending habits have made the biggest difference in your budget? I'm looking for practical changes that don't require extreme frugality but still add up over time. Which smart spending habits give you the most bang for your buck in terms of savings? How did you develop these habits, and how long did it take for them to feel natural?
