Now wait just a minute. Are you telling us that you are selling three (not one, but THREE) isolation feet for 18 bucks without pages of text that references every known science from particle physics to quantum mechanics to non-linearities of the space-time continuum as reasons for why they will work better than anything else that has ever been made? This is unprecedented and frankly, an outrage!!. You membership in the high-end community should be rescinded immediately. As an alternative, you might consider adding several zeroes to your price in order to save your reputation.
