The author presents the findings of empirical studies focussed on changes in relations of retail prices within selected commodity groups. Differentiation of dynamics of prices for particular products observed in practice is not closely connected with growth of their production costs or with market disequilibrium. The main determinant differentiating this dynamics is a desire to achieve the highest possible profit per product unit. That reflects a desire of companies to attain an indispensable financial effect allowing them to fulfill their financial commitments towards the state budget. Such "fiscal orientation" in the pricing policy of companies does not create conditions that would favour rationalization of price relations themselves.
