To close a sale, the prospect must see themselves buying from you. In order for this to happen, you must do two things.
First, enter the conversation that is already happening in the shopper’s mind. For a shopper buying out of necessity it is probably a conversation about cost, wanting the problem to go away, and avoiding a mistake. For a non-necessity shopper the conversation is probably more about being is a hurry to possess the product or service. It is really like a fix to a junky.
Second, create a mental picture, in the shopper’s mind, that defines success as a result of buying from you. To do this you must first understand what success looks like from the shopper’s perspective. For the necessity buyer the picture may not involve what they are shopping for, but include instead the result of the purchase. If the shopper’s car is broke down and they are having problems getting to and from work, the picture might be how, after buying the repair part from you, the shopper is driving their own automobile to work without worrying about a breakdown. The product or service is probably not an important part of the picture.
For the non-necessity shopper, the picture may be that of the shopper using the product or service in the way they have presented the need. For example, if the shopper discloses that they want to be able to get their email anywhere, anytime; you will want to present scenarios where the shopper can visualize themselves using this new smart phone in various locations, while at the same time receiving an important email. The product or service is an important part of the picture.
In any case, the shopper and their motivation is the driving force behind any purchase they might make. You and the product you sell is not the driving force, but instead the road or map the shopper must follow to successfully meet their need or desire.
