Karstadt's book departments have been operated since April 2008 as “shops-in-shops” by DBH Warenhaus (Verlagsgruppe Weltbild/Hugendubel). In Karstadt's premium stores (such as KaDeWe and Karstadt's Hermannplatz store in Berlin) these book departments operate under the “Hugendubel” name and in all others as Weltbild. Further companies who are Karstadt tenants and operate independently while renting Karstadt's checkout/payment system include WMF, Rosenthal Porcelain and the drugstore brand Müller. In October 2007 the Handelsblatt reported that Karstadt was considering taking over the Kaufhof department stores from Metro AG, a deal which would have made the company Europe's second-largest department store group after Spain's El Corte Inglés. In 2008 Gravis announced the abandonment of its unprofitable cooperation with Karstadt in two pilot stores in Düsseldorf and Lübeck which had originally been envisaged for all 90 stores. In the same year Karstadt started cooperating with the fashion designers Kaviar & Gauche and Kostas Murkudis.
