After adding Evert's motorcycles and a Ford Model T to its transportation reserve, the company began to consolidate its deliveries so that all packages for a specific neighborhood would be loaded onto the same vehicle, maximizing use of resources while keeping expenses low.
The business grew quickly, thanks to the company's dedication to its customers. Jim Casey and his colleagues became experts in fulfilling the needs of the drug and grocery stores. In most cases, the company's employees worked onsite at the stores to ease distribution efforts.
The final founding member of the company, Charlie Soderstrom, joined the firm in 1916. With his expert knowledge of automobiles, he helped manage the company's rapidly expanding fleet of delivery vehicles.
The young company's visionary leaders saw a new opportunity to promote their business, and ultimately persuaded retailers to outsource delivery services to their company. The executives had to create an element of trust and credibility for the retail stores to agree, and those businesses had to overcome faith in their own systems in order to cede to a third party. In 1918, three of Seattle's leading department stores became customers, abandoning their own internal delivery efforts, and turning over business to Merchants Parcel Delivery.
