My biggest savings has been in cleaners. i do not buy anything but laundry, dishwasher cleaner, and toilet bowl. I clean my counters with hydrogen peroxide, it is cheap and a very good cleaner. i clean my windows with vinegar. i clean my showers with lemon juice. You can mix baking soda, vinegar & lemon juice and make a cleaner for just about anything. For my fake wood floors, I use diluted peroxide. To make it all smell good, i buy a bottle of scented oil and i add one drop to the my made up cleaners.
I put back $20 a paycheck to savings for medical expenses and i just let it accumulate so when things happen, there is a little pot to draw out of.
For meat, my husband hunts. We process about 2 deer a year and we have them make sausage and hamburger....We mix the deer meat with brisket to make the best hamburger meat...even better than the real thing since it is so much leaner and yet still has a great flavor. the sausage is about $2.00 a link and we usually get about 100 links, that is about two links a week for a year. and the hamburger costs us roughly 80 cents a pound and this year we got about 160 pounds, that is enough for us to use 3 pounds a week for a year!! Saves us loads!!
For my other meals, I make large meals such as chili, roast, beans which are cheap but cover several meals. My husbadn will grill a whole chicken and that covers at least 2 meals for 4 and the that is 8 meals which is .50 each per meal for meat.
For snacks, I buy pretzels, chex mix, cheese nips, popcorn. I then seperate and put a serving into a zip lock snack bag then store in cabinets. This stops us from over eating on the snacks and going through them too quickly. I do not buy chips, but when I do, I do the same and they definately last much longer!!
I stopped buying things for my kids and started giving them an allowance so that they can learn to managge their own money. I give them 2.50 a week and I keep track of it on my phone. then when they are asking for things, they get only what they can afford and this has cut back on my spending too since I really didn't see how much it all adds up.
I have friends and we coordinate movies, so if i rent a redbox and I watch, the next day I take it to a friend and they watch it & return. Then they do the same for us. We also borrow each others DVD's that way it expands our libraries.
i do not buy books either, I go to the library. you can even check out kid movies at the library.
for laundry, we wear our denim like 3 times before washing. Same with towels. this saves water soap and labor.
i buy large juices and put in my kids thermoses to use instead of juice boxes and the thermos keeps the juice cold so that it lasts longer and less wasted. Less garbage in landfill also.
This is all I can think of right now.
