I have a ton of money saving tricks. I don't go shopping for fun, especially not to malls. Seeing all the stuff set out to entice me to buy it just makes me want what I don't need and can't afford. The majority of that stuff would end up being clutter, which I dislike.
Similarly, I don't watch tv shows that have commercials. That way the ads don't entice me. It is also cheaper to have Netflix and Amazon Prime for television -- our middling cable bill used to be over $100 a month.
I buy a lot of clothes at Goodwill. It is amazing how many nice clothes that seem new are there. I've also had good luck on eBay. I don't have as many clothes as many people do because I see no point in having more than I need. I am not a clothes horse.
I don't buy junk food or drinks. I comparison shop, stock up when things are on sale. I cook and bake from scratch. We have an Aldi, which helps a lot with saving money on groceries. I eat a healthy diet, heavy on vegetables, lower on protein.
I don't eat fast food or eat in restaurants very often. Fast food is not healthy, and I can cook better food than most of the restaurants around here.
I combine errands when I go to town (a 20-mile round trip) to save on gas. I make sure our car is well-maintained so it lasts longer.
I take care of my things so they don't have to be replaced often. When I buy something, even from Goodwill, I make sure it is high quality so it will last longer.
I read a lot, so I am always getting free books for my Kindle, from libraries and from Amazon. The upside of this is that I have discovered a ton of great authors this way.
I keep track of our finances for business and home on Quicken.
I keep in mind that what I spend my money on indicates what is important to me. It helps me not waste money. Things I think I want very much go my wish list at Amazon. They just sit there until the urge goes away. Am I really going to make homemade ice-cream often enough to justify buying the machine? No! Ice-cream is not one of my favorite foods, and everyone else in the family is happy with store-bought (buy one, get one free).
I grow food -- tomatoes and other vegetables, herbs.
I keep my weight stable and do not keep clothing from the past that is a larger size.
I routinely go through our belongings and give to thrift stores everything that is not needed (ie, not used often or seasonally).
I don't use credit cards. We have one, but it is for emergencies only.
