Why is Camp-co Successful?

For those of you that are not familiar with this convenience store it is located in Keene, NH on Winchester street. This store sells everything from drinks to specialty tobacco. Which is not out of the ordinary for such an establishment.As i was passing by this convenience store on my way to class i started to wonder how much marketing was done to make this establishment so successful. After belaboring the idea in my head the best conclusion that I came to was, the owner had to do next to nothing to market this business due to the location.
The location for such an establishment is perfect, because it is set no more than 100 feet from two dorm buildings one of which being a freshmen dorm. I believe that this allows the business to market itself, just by the location alone. Throughout the years this store has been a common landmark that most any college student can refer to.
Which brings me to my next point and that is the power of word of mouth. Word of mouth in my opinion is by far the  best form of advertising and marketing for a business. That is if all goes "according to plan". I say this, because you can't force your customers to speak highly of your business, it happens on its own within outside conversations of individuals. I feel as though this is what happened to Camp-co. Seeing as how it is based feet for campus and at least three dorm buildings, it allows college students the convenience of referring to it as a landmark, using it for an establishment to find a quick fix of chocolate or ice cream when all other establishments are too far away, or closed at that time. Thus, allowing for the power of word of mouth to spread. This is a perpetual form or advertising and each year since it is based steps away from a freshmen dorm, they have a new student body to tap into.
I feel as though Camp-co would not be nearly successful as it is today if they were to be in a different location. It would be just another store based on a long common street that is used for commuters.

Do you feel as though the location makes Camp-co or is it something else?
