My husband and I live pretty frugally since I am a housewife and he brings in the only income. This is a choice we made but some of our practices may spark an idea for you.
1. Make all of your cleaning supplies. White vinegar is almost all you need! I use vinegar and water to clean the bathroom and use baking soda in the toilet to scrub and then add vinegar.
I also make my own liquid foaming hand soap. I mix 1 Tbsp Dr. Bronner's liquid Castile soap with 8oz water...that's it! I didn't go out and buy a special dispenser, just used an empty one from a store-bought soap.
2. Make some of your own hygiene products. I just started making body wash, shampoo, and "conditioner". I need to tweak the recipes a bit but it saves a lot of money and is safer for you! Using Dr. bronner's Castile soap as a base makes it easy.
3. Evaluate your food budget. Determine if you can shave off money from your food budget by buying less processed food or different cuts of meat. A great example is purchasing a whole chicken rather than boneless skinless breasts. You can either cut apart the different chicken parts and separate them all out to use for different meals, or you can cook the whole chicken at once. I simmer a whole chicken for 1-2 hours which yields a whole batch of broth, then debone and shred the chicken, then simmer the bones in another pot of water and get a full second batch of broth. You can freeze the broth however you like...I like to freeze it in 2-cup portions (wide mouth pint jars). Each 15oz of broth in the store is about $1 so it saves a LOT, not to mention it tastes so much better!
Also consider making vegetarian meals at least once per week. When you do eat meat, make it part of the main dish, not the entire main dish (don't have a chicken breast, but have a dish with chicken IN it).
3. Buy less expensive makeup. I used to wear high quality makeup but we just can't afford it with me not working anymore. Well, we could, but that eats into our savings so now I wear cheap makeup. I don't like it nearly as much, but it's worth the savings.
4. Do Swagbucks or other things like that (I think you can do it in Canada). I used to only earn enough for $5
Amazon every month or two, but now I'm earning around $15-$20 per month.
