Beriozka was the overall name applied to two chains of state-run retail stores in the Soviet Union that sold goods in exchange for foreign currency. Beriozkas sold luxury goods such as chocolate and caviar that were often unavailable or unaffordable in traditional Soviet markets and shops. In English-language advertisements and signs, the spelling was always "Beriozka" rather than the more conventional transliteration "Beryozka." Beryozka existed between 1964 and 1990 up to the point of the Soviet Union dissolution.

Intershop was a chain of government-owned and operated retail stores in the German Democratic Republic in which only hard currencies could be used to purchase high-quality goods, usually from or associated with Western countries. The East German mark was not accepted as payment. Intershop was originally oriented towards visitors from Western countries, and later became an outlet where East Germans could purchase goods they could not otherwise obtain. An unintended consequence was that ordinary East Germans had some insight into the selection of goods available in the West, which they could then compare with the rather limited offerings available in their own country.
