I agree with this suggestion. They do offer smaller containers and fewer in number but I don't see them in stock right now.
As for the effectiveness, of this particular product, I think it works wonders on so many things. It isn't a miracle cure, which is what I think people expect. It does require some real scrubbing for most things, it isn't just a "wipe on and see a miracle" kind of product.
I find this indispensable in my home and I hope they never stop making it!
