Maybe ordering online will be less costly. The most recommended water conditioner is Prime.
Was reading a 1985 Tetra Press book called "Maintaining a Healthy Aquarium". I'm an old school water keeper and still use most of the old approaches. Anyway, in the section on chlorine and chloramine, I found the following:
"Chloramine can be removed either by aerating the water for a much longer period than is usually required to disperse chlorine (between two and five days, depending on circumstances) or by using a chlorine remover together with a zeolite or zeolite/carbon filter."
Not sure I'd want to go the trouble of aerating a bucket of tap water for 5 days, guess it's much easier to use a remover in liquid or powder.
Just a thought.
