What are some small daily habits that surprisingly save a lot of money without changing your lifestyle too much?

I’m curious about simple, realistic habits people use to save money that actually add up over time. For example, I recently discovered that running my ceiling fan in reverse during hot weather keeps my room cooler and reduces my electricity bill by nearly half compared to using the air conditioner.

Do you have any other creative or unexpected money-saving tricks that really work? I’m especially interested in those that don’t require major sacrifices or lifestyle changes.
