Wanamaker’s business philosophy, which dominated the retail operations of his department store, relied on fixed prices and guaranteed customer satisfaction. His department store included the first in-store restaurant – now a staple at most department stores in New York City. Wanamaker is also believed to have invented the White Sale, a marketing strategy in which the store deeply discounts merchandise at a time when sales are slow. Wanamaker’s treatment of his employees was also revolutionary – he gave his employees free medical care, education, recreational facilities, pensions and profit-sharing plans before such benefits were considered standard. Wanamaker’s decision to link his store to the new subway can be seen as another revolutionary (and successful) effort.
