Music is just one data point suggesting a rapidly changing retail scene. Enterprising retailers could transform the traffic brought by roads and bridges into customers. The medieval London Bridge is one of the more famous examples of a bridge that was covered with buildings serving as retail stores, residences, and even churches. In 1846, Stewart opened the Marble Dry-Goods Palace on New York's Broadway, which by 1862 had taken over a full city block and was the largest retail establishment in the world. This chapter explores the range of retail transactions in turn. It outlines salient dimensions of retail location strategies, and closes by positing a relatively simple model of retail location to suggest some of the complexity involved. The chapter focuses on places for selling goods. Although retailers demonstrate many of the same macro-preferences as non-retailers, the way such preferences play out is markedly different. The buyer can be mobile and go to a fixed store: traditional retailing.
