According to the rules of consumer behavior, there can be five types of non-buying customers- the complainer, the overtly excited, the expert, the pessimist and the staller. It is comparatively easy to control or regulate the behavioral patterns of the buyers, however, the behavior of the non-buyers is not dependent on personal experience of using a particular brand or a product. This sort of a mannerism is influenced by preconceived notions formed by the opinions of other people or a perception formed by the advertisement or marketing of the brand. A non-buyer may encourage or discourage in buying a product that he or she has never experienced.
The complainer – A complainer is a category of non-buying customer who will always whine about a product and pick out its flaws in spite of not having used it. I have exhibited such a behavior in case of Dove soap bar. The Dove bar soap had never entered my premises, however, I had the idea that the lather does not wash off completely and leaves behind a soapy after effect on the skin. I considered all their advertisements of skin care and the fact that Dove soaps are healthy for the skin, a hoax. This opinion was highly influenced by my sister who used Dove soap bar on a daily basis. She had this particular viewpoint and since I trusted her, I contracted the same idea without having first-hand experience of it.
The overtly excited – This category includes people who do not have the time or the ability to help others. These individuals do not want to scrutinize the product and are positive about any opinion that is asked of them. I was once asked by a friend regarding my stance on the purchase of a Gucci purse. She was confused about it and inquired of me if she should buy it or not. Despite the fact that I had no clue about how good the purse would be or what utility will it hold for her, I blindly encouraged her in buying the product. My opinion was influenced by the high-end advertising of the brand and the entire market going gaga over it. I had assumed that the bag was good, it did not have flaws and that it was a very important item to possess.
The expert – Most of us love expressing ourselves. It is immaterial if the opinion is authentic or correct, the idea should be expressed. Many of us have no clue about the flaws or the benefits of a certain product and yet we form a notion about it. A similar incident took place when I was advising my friend on her purchase of a Blackberry Phone. I had never used a Blackberry ever in my life, so it is likely that I would not have any information about its pros and cons. However, I took it upon myself to pin-point the positives of Nokia (which, by the way, I had not used either) to my friend over Blackberry. All of this was coming from my uncle who had used the Nokia phone. I was just propagating his speculation of it and giving her my expert advice on how Blackberry was worse off than Nokia.
The pessimist – The term is self-explanatory. It talks about someone who finds flaws in everything and discourages others in doing (in this case buying) something that they think is not up to the mark. I am a pessimist when it comes to buying electronics online. No matter how advanced the offers and the services might be, it will never be able to help me get rid of my prejudices. Amazon had a great sale coming up at the same time my mother wanted to buy a hair dryer, online. I convinced her against her will and made sure that she does not venture into buying electronics through any online portals. The funny part is, no one in our family (including me) has ever bought any electronic appliances through Amazon or any other website. I am somehow programmed to buy such products only if I have physically seen them.
The staller – As the name suggests, a staller is a person who postpones your interest in buying a product. I had exhibited such a behavior when my father wanted to buy an I-Pad. It was the latest model that was in for sale. However, it was high time I gave my father some advice going against the natural flow, but at the same time, I had no idea about the facilities provided by the particular brand. I accepted my lack of knowledge in the field and asked to wait until the price of the product went down which would not have been possible until the release of a new model. It was pretty evident that it would not happen in a year so basically I had hindered my father from getting himself a treat because I was not getting any.
