I love mineral oil. Always use it for difficult sheds. Aside from the desired effects on mites or sheds, I think it also is beneficial to the animalís skin. Always had very positive results with oil. I know what you mean on the $11, but people sometimes hit hard luck and already have the animals. Not much you can do then, but try to scrape by cheap as possible.
