Final answer:
Travel stop plazas along interstate highways are an example of a non-traditional retail location, offering a convenient shopping experience for travelers, and contributing to the diversity of the monopolistically competitive market.
Step-by-step explanation:
An example of a non-traditional location that retailers are selecting is travel stop plazas along interstate highways. These locations are becoming more popular as they provide easy access for travelers who are on long journeys and need to stop for essentials, food, or to take a break. Unlike traditional settings such as multi retail store shopping centers, suburban shopping malls, outlet malls, and local corner stores, travel stop plazas represent a shift in consumer patterns by catering to the needs of mobile and time-constrained shoppers. In the context of market competition, these non-traditional retail venues can be seen as part of an increasingly monopolistically competitive market where a variety of similar but not identical products are offered by different vendors to meet specific consumer demands.
