If at all possible when presenting a complicated and expensive product, get your prospect into a quiet area where interruptions will be at a minimum. This is not always easy, but if your prospect’s attention is half on you and half on what’s going on around you, your chance of success drops significantly. Why do you think the finance and insurance person at a car dealership has a private office? They are going over a lot of details with their customers and also trying to sell them additional warranties and super-duper seat protection. Just like you are.
