I have no debt and I don't spend much.
Ditto. Of course, that's cursory.
You want examples, yes? I have a sewing machine, can and do use a needle and thread, duct etc. tape sometimes. Also a washer and dryer. But unless it's raining, I hang my laundry outside to dry.
Have no kids, no wife, no GF ATM, but I want to change that. They say "two can live as cheaply as one!"
I roller skate or bicycle unless I absolutely need to drive. Except for only one time in my life (about 3 years ago), I've done all repairs personally on the bicycles I've owned. I change my own oil. Fix my own skates.
I fix things instead of buying new ones if possible.
I fix things instead of calling a repair man or company whenever possible. I have a lot of tools, hand tools, power tools, and a lot of hardware. I've accumulated it all gradually over many decades. I use my imagination. Fixing things can be fun!
I'm a gourmet cook when I care to be, with mostly simple tastes, rarely eat out. I buy food (often in bulk) from cost effective sources.
I get my movies from the library, usually, i.e. cost = zero.
No subscription TV, Netflix etc. Get TV from rooftop antenna, HDTV with PC card + it's free software = timeshifting, no commercials.
I take a shower once a week.
I reuse floss.
I eat almost entirely off the dollar menu.
I dress like a hobo.
I use slickdeals and coupons.
I bought the entry level McLaren.
I flush the toilet sparingly.
I shop at the $0.99 store.
I use a swamp cooler instead of air conditioning.
I put on more clothes rather than use a heater.
I do almost all that stuff, don't know what a McLaren is. A car?
No dollar menu for me, I don't eat there at all.
I have an air conditioner in my bedroom only but rarely turn it on. Instead I turn on a switch which activates a couple of 200ml silent computer fans that blow air in from outside at night in the warm weather months. Cools the room by least 5 degrees usually.
I waste almost no food, cook from scratch. Grow my own tomatoes, winter squash, some herbs. I can food. I make my own coffee, never at a coffee shop.
I buy my glasses online.
Generally, I use my car rarely and piggyback errands. I pretty much stick to my shopping lists rigorously. I use the credit card that gives me the biggest discount for a particular purchase. I use credit cards for all purchases possible. I never carry credit card debt.
My gym (24hour fitness) had a special on some years ago where I paid out about $750 for 3 years IIRC, the kicker being I got unlimited membership for the indefinite future for $100/year. Still going there several times/week. I use the machines and weight room, but have access to free classes there and have used that a lot (yoga, pilates, there are others).
The easiest way to save money (to me) is just to delay purchases. A simple example is with haircuts. I could get a $12 haircut every 3 weeks. That would cost me $208.56/year.
Dude, I cut my own hair yesterday. I bought a hair cutting kit some years ago, haven't looked back. I do have a hand held mirror so I can see the back of my head to check for imperfections at the end of the process. I think I do a pretty good job.
