17. Baking Soda
Thank God baking soda is so inexpensive! You can use it for pretty much anything you can think of- if the plethora of internet hack videos are anything to go by. You can make your own toothpaste, use it as deodorant or mouthwash and you can clean the house (including your refrigerator) with it.
So it’s very unlikely that the stuff you’ll find in the grocery store will be more expensive than the stuff in the dollar store. Don’t be fooled into thinking you found a good deal!
