While the hardlines industry continues to change, the basic function of purchasing products from manufactures and selling them to dealers has remained unchanged since Wallace's founding. The role of the wholesaler has greatly expanded throughout the years to include offering many innovative dealer services. Store merchandising, affordable dealer advertising, inventory control systems, and clean modern stores became dealer necessities. In 1963, Wallace became affiliated with PRO Hardware in Stamford, Connecticut (now the PRO Group, Inc. located in Denver, Colorado) and now markets the PRO Group program in an eleven-state area.
