Visit http://tryahsensitive.com/ for a free sample of Arm & Hammer sensitive toothpaste. I imagine this is "while supplies last." I requested my sample this morning. They require that you confirm the request by clicking an email link (they send the link after you request your sample). When I confirmed I got a message that they'll be sending my sample and it should arrive in 4-6 weeks. Happy freebie gathering and money saving!
