The most expensive part of this recipe is the fragrance oil and the packaging. We purchased the distilled water from Cash and Carry, a local restaurant supply. I did not include the price of labels in this equation because they can vary so greatly depending on how you print them, where you get them printed and what size they are. Bramble Berry carries water resistant labels that would allow you to get at least 10 labels for our 8 oz. bottles from each sheet.
