I was a little confused cause I got roped into upgrading to clinical strength, thinking I was then purchasing two bottles for $58, one of each strength. When my order came, I got the clinical strength only for $58. I am living on a limited income and would never spent that much money on one bottle. I tried the product on my neck and felt no relief. I will try it again but will never purchase it again. I heard such great reviews from the radio show you sponsor, but am sadly disappointed in the way you sell your product.
