The essay above could be summarized in six stages of purchase decision. All the three types of purchase experiences include the six stages. Each and every stage of purchase decision is important in making the correct decision for the product. The major six steps are need recognition, information search, evaluate the options, purchase decision, actual purchase and the post purchase evaluation. It is important to follow all the steps in order to make the most appropriate decision for the product. The three major purchase decisions discussed in the essay are minor re-purchase, major purchase and major re-purchase (Griskevicius & Kenrick, 2013). Different types of purchase decisions are taken for different products. The complexity of taking the decision depends on the type of the product and its need and worth for the consumer. Decision making is a process which has various aspects and each of this aspect is governed by different factors. However, the Consumer behaviour theories apply to all types of purchases, irrespective of them being big or small. With the advent of internet, the online image of any brand plays a significant role in the decision making process of the consumers. Moreover, the direct feedback and review of the product available on the internet helps the consumers on one hand, and on the other hand, it also helps the companies to improve on the design of the product based on those feedbacks.
