I'm happy with what I have now
Strategy : This response is more of a challenge.Many people have the "If it ain't broke don't fix it" mentality and are afraid of change.Complement their loyalty then have prospects think outside the box and explore that there may be something better than what they have by offering a free trial or product demo.
Response : That's great. I appreciate your loyalty.A lot of people are interested in looking at other potential product offerings...Just to compare.You may find us a better match for you needs,which would be great,or if you decide to keep what you have you can feel good about your current situation.How would you feel about attending a product demo to compare?
