 Many premium goods could be bought either in a black market or only in special stores using foreign currency generally inaccessible to most Eastern Bloc citizens, such as Intershop in East Germany, Beryozka in the Soviet Union, Pewex in Poland, Tuzex in Czechoslovakia, and Corecom in Bulgaria.Much of what was produced for the local population never reached its intended user, while many perishable products became unfit for consumption before reaching their consumers.As a result of the deficiencies of the official economy, black markets were created that were often supplied by goods stolen from the public sector.
