$40 for distilled/deionized water? You got ripped.
should have been at most $4-5 bucks.
I agree with RF about not running water long term. Use of distilled water only is to get you to a place where you can do the flush safely. Use of water with no anticorrosives in place will lead to engine damage. You only have a day or two if running on distilled water only until you flush. Follow my sig for the link in flushing coolants.
