In 1884, confident enough to open another store, Sum partnered with his longtime friend Fred Morgan Kirby to open a store in Wilkes Barre, Pennsylvania, a neighboring town to the west of Scranton. Fred had been working as the head of wholesale operations at Augsbury and Moore of Watertown, New York. Each man put up $600 to launch the Wilkes-Barre store called "Woolworth and Kirby". Fred managed the new store and, while sales were initially poor, the store soon caught on. By 1887 he used his profits to buy out Sum and expand the store under his name; Sum and Fred remained the best of friends. During this time, Frank was expanding with more stores. Sum's approach was different; he worked to perfect the look and feel of his Scranton store. It had mahogany counters with glass dividers and glass-fronted showcases. The store was brightly lit, new, and the wooden floor was polished to a lustrous shine. The layout was soon adopted by Frank for his F. W. Woolworth stores and became the standard as the two brothers persuaded family members and former co-workers from Moore's to join them in forming a "friendly rival syndicate" of five-and-ten-cent stores. Each of the syndicate chain's stores looked similar inside and out, but operated under its founder's name. Frank Woolworth provided much of the merchandise, encouraging the rivals to club together to maximize their inventory and purchasing power.
