It's a matter of one's perspective. If you are properly connected, you should be able to buy nitric acid for a price in the neighborhood of $5/gallon. That, of course, is in bulk packaging, likely available (now) only to licensed operations. In the early 90's, I was paying $207 (American) for a 55 gallon drum.
