Direct sale and its importance in retailing

The main goal of this Bachelor's Thesis is to find out what are the main reasons for a customer to buy a product, and what makes difference in making decision for a client. "Navigate, selling the way people like to buy", is the book which will be used for theoretical part, from author Dustin Hillis. Dustin Hillis is a very successful sales person and divides customers into 4 different groups based on style they like to buy products. The same method used for example Lee McCroskey in his seminar "Becoming a Chameleon". I will use those 4 types of customers in first part to compare theory with my experience from direct sales. For practical use I have chosen Southwestern Company. I will use mainly my own experience and notes that I collected last 3 years. I personally sold products to 850 customers in 240 days. In last part of this thesis I will analyze how useful is theoretical knowledge in particular sales situations and also types of customers
