It approximately 3-4 % from the general retail in Russia (in Ukraine hardly it is less, the market is developed less and now deep crisis) and to 10-12 % in the USA and other developed countries. The average level in the world makes approximately 6 %. A unique exception, last year in Ukraine because of a deep economic crisis the market has not grown in a dollar equivalent, but for the local companies it is chance to overtake missed earlier.
