Why is there such a price variation in toilets by American Standard with same specifications but different model numbers. Sometimes when you are on American Standard website and viewing a specific toilet, they provide a long list of model numbers on top left hand side for that toilet. Is this lunacy? For example, I looked up Cadet 3 Right Height Elongated 1.6 gpf toilet, I found different models with differing prices with the same specification. Then, again, different stores had vastly different prices. Could there be a difference in quality ? I am lost.

Cadet 3 is very good
