[1] In 1931, the 50-store Economical Drug chain, also based in Detroit, consolidated with Cunningham, which at the time had thirteen stores.

[1] An effort was made by the United States Department of Justice to dissolve the Kinsel merger, citing that it was in violation of the Clayton Antitrust Act.

[10][11] Cunningham's also had some small drug stores branded as Schettler's in major hotels, such as the Sheraton-Cadillac in Detroit, and at high-end retail, such as at Somerset Mall in Troy, Michigan.

The chain sold off twenty-eight of its Michigan stores in 1982 to a private company, which re-branded them as Apex Drug.

[13] Three years later, most of the Apex locations were sold to Perry Drug Stores, another chain based in the Detroit metropolitan area.
