I just saw the commercial for the Instaflex topical pain reliever. It leads you to believe that if you call a certain 800 number you can get a free tube with free shipping. It's a hook because you have to buy two tubes to get one free and free shipping. The woman I spoke too was not straight forward about how the offer worked even though I kept telling her I was only interested in the free tube and she kept interrupting me. So, unless you want three tubes of something you don't know even works there is no deal. You can purchase just one whopping 2oz tube for around 20 bucks plus shipping.
