What we teach here is not intended to save you money on chemistry. It may or may not but that's not the point.
We teach you to understand how to manage your pool water chemistry. You can certainly go to a pool store and they will be happy to do that for you....you'll have to decide how much that costs. Their free testing is usually worth exactly what you pay for it. If you are happy with that method and it's working for you, you probably have nothing to gain by reading further.
Conversely, you can take pool management into your own hands by learning the chemistry and not being dependent on the part-time college kid telling you how much you need of each of the products they want you to buy.
