REWE restructures: the three-tier structure (retail - wholesale - head office) is abandoned in favour of a more efficient two-tier model (retail - head office). The REWE wholesalers Hungen, Efferen, Korschenbroich/Erkelenz and Koblenz transfer their business operations to REWE-Zentral AG. These are then reorganised as the branch offices Hungen and West. Just ahead of German unification, the first REWE stores are opened in Potsdam and Weimar during the last days of the German Democratic Republic. In the southern and southeastern regions of Germany, the 399-store base of co op AG and the co op warehouse in the Neuhausen district of Stuttgart are acquired.
REWE-Handelsgesellschaft Leibbrand oHG acquires the company Deutscher Supermarkt Handels GmbH, Düsseldorf, which operates food retail chains such as Deutscher Supermarkt, Desuma, Hill, and Otto Mess. REWE enters the travel and tourism business by taking over a 50 per cent stake in the travel agency firm ATLAS-Reisebüro GmbH, Cologne. At the time of its takeover in 1994, ATLAS REISEN operates some 300 travel agencies.
REWE acquires 51 per cent of the food chain Cornelius Stüssgen AG, Cologne. The remaining 49 per cent are acquired by REWE-Zentrale in 1989.
The Kaiser+Kellermann Group, based in Kirchhundem, Germany, joins REWE with its Globus hypermarkets. REWE takes a 75 per cent stake in the company in 1988.
