The topic of this paper represent factors that influence the choice of the point of sale and shopping on the example of grocery stores. The paper describes in detail various factors that have an impact on consumer behaviour. The aim of the paper was to investigate which factors have the greatest influence while choosing a store where the purchase will be taken and to roughly determine how the average purchase looks like. The research was conducted by an online questionnaire on a sample of 111 respondents. According to the obtained results, it can be concluded that the most significant role while choosing a store is played by the physical environment in retail, specifically the location of the point of sale itself. Respondents visit stores several times a week, and shopping takes an average of 15 to 30 minutes. Their basket mainly includes fruits, vegetables, cereals, dairy products, meat and personal hygiene products. When choosing a product itself, they pay attention to the price and composition of the product, while they prefer stores that are close to them, have favorable prices, available parking and a wide selection of products. As for social influences, customers have shown that when choosing a store or when choosing a certain product, they respect the opinion of close people, but they prefer to make the purchase by themselves. One of the personal factors common to all respondents is motive. Respectively, for each of the consumers, buying in a grocery store respresent the purchase of basic foods necessary for life. The main difference is that each person is different. It can be said that everyone adjusts their purchases in accordance with the means at their disposal and buys the food that suits their budget and lifestyle.
