can supermarkets serve the public interest? First of all, large supermarket chains can provide a large number of product options to the public. To begin with, there are quantities of products in supermarkets since thousands of farmers and suppliers offer products to a small number of supermarkets. For example, in United Kingdom, each of the four supermarkets needs 7000 suppliers, which ensures a variety of products (Young, 2012). More specifically, statistics on supermarket chains from around world support that on average, every supermarket stores 47000 items (Consumer Reports Magazine, 2014). In addition, according to Berger, Draganska and Simonson (2007), the diversity of brands in supermarkets also offers plenty of options to customers. Thus, numerous products and varieties of brands make it possible for customers to have many choices. Nevertheless, some critics argue that there are too many products which make customers feel confused and waste time to make a choice. Studies show that the average American spends more than half an hour per day shopping in supermarkets (Goodman, 2008). That is, many customers spend long time on shopping in supermarkets because of too many choices. Furthermore, according to Schwartz (2006), some customers will be under pressure and feel dissatisfied when they face so many product options in supermarkets. It may be true that choice overload exists in supermarkets and this will make some consumers feel anxious. However, most customers still require a wide range of products to choose. That means more products in supermarkets are better for most customers (Rana, Osman and Islam,2014). Therefore, it is clear that large supermarket chains serve the public interest because they provide a great many products to the public.
