"Thanks for the information you recently sent me on Medicare supplements. My first reaction when I opened the envelope was that this was another gob of hard to understand information that would leave me even more confused after reading it. This wasn't the case and I am sure you have heard the same from others, that this was the clearest description of the different options and makes it easy to decide what course to take.
I decided early on to buy from somebody here in Salem and would gather all the info so I could educate myself on Medicare Supplements before dealing with them. Your packet changed my mind and I will definitely purchase from you."
This is a common response that I get from my approach to help people understand their choices before they make a purchase.
