I'm no professional, it's been years since I took an accounting course, and I'm not earning a lot of money, but I've learned a few secrets to save a little money.
Buy instead of rent. It looked into it and it would cost me $70+ to rent a carpet cleaner. I like to clean my living room carpets at least once a month, so I found one on sale for $95 and it came with cleaner. Even if I only rented once or twice a year this will save me money.
Make it at home instead of buying it. Hats, bread, scarves, pictures, there's so many things you can just make at home. I got a bread maching 8 years ago and I'm still using it for fresh bread and buns. I save over half the cost per batch, usually more, and we get to eat it fresh from the oven. I can also get enough wool for 4 scarves for $10, much cheaper then buying and you can personalize them. Or just sell them and buy the things you need.
Save your change.. Empty the change out of your wallet or purse and put it in a piggy bank (I even found one that's actually a pig and he oinks when you put money in) If you want to go one step farther save all your $5 bills too. You can save $20+ every month, if you only use cash then you'll save even more.
Get dryer balls. The investment (I got mine for $30 from Norwex, wool) will save you 1)dryer time and therefore energy, 2)dryer sheets, 3)fabric softener. I worked it out to about $5-$10 savings per month. What a great way to save an extra $100 year and actually waste less time and it's less work since they just live in my dryer.
Use less cleaning supplies. I started using cleaning mix from the Farmers market, natural and lasts forever, and now I"m using Norwex as the cloths last years and clean with just water. Yes I still use soap some places, dishsoap mostly, and we are having fewer headaches and my house smells cleaner.
Vinegar for everything! It cleans washing machines, dishwashers, sinks, microwaves, It can also help with removing the smell of cat pee (not spray, nothing gets that out!) and unclog drains with a little baking soda.
Buy better quality items, just invest the money in something that will last. This may sound counterintuitive, but I have $10 shirts I bought 10 years ago that still work and fit, but I've got $3 shirts from last year with holes. Sometimes when you get less expensive items you just end of buying more of them. Get one good pair of boots instead of a few pairs of cheap ones, your feet and your wallet will thank you.
Bulk buy. Care for you stuff. The better you maintain it the longer it'll last. Close your curtains when it's hot or cold. It'll help regulate the temperature in your house. Use vinegar to start dissolving the dishwasher tab, it cleans better and you won't be as angry opening a dishwasher to find dirty dishes all the time.
Buy products that have multiple uses. A pan that goes in the microwave and oven, a sports band that has a watch function, a kitchen mixer that has useful attachements so you don't have to buy additional gadgets.
Sheets make great furniture covers (splurge on pretty ones) and they help your furniture last longer.
