Baking Soda
We could buy a bundle of baking soda in warehouse stores such as Costco, and it would only cost for around 85 cents per box. We could stock up whenever we want because of how cheap these are, and it would not get spoiled. This way, we would never run out of baking soda.

Shampoo
Shampoos were typically applied to wet hair, massaging the product into the scalp, and finally rinsing it out. Even though the shampoo was not branded, the ones without brand do the same stuff that the expensive ones did. We could also save more money by buying them from the dollar stores.
