The retail market of consumer goods on a national scale in recent years has taken “fire” point of fully competitive - monopoly - political interest, and it was pointed out as a typical example of a highly concentrated industry. It is a peculiar and very complicated institutional form, known as to the market constellation and market structure. In this respect nothing is theoretically questionable. It is quite clear that we speak about the number of participants in that market on the supply and demand side. On both sides it is possible theoretically that there is one (monopoly), little (oligopolists) and many (polipolists) bidders or buyers. Starting from this position, to the simplest understanding of the essence of this research, in paper are described and designed possible market constellations.
