In Response to Kevin Provost

So why are they closed when they could be having their biggest day of the week???

This video is an example of what your explaining. Banks should be open after the normal work hours because everyone works during the normal work hours and are not able to go to the bank. Motorcycle stores are probably closed on the weekends because the workers need to have a break from work to. It wouldn't be fair to have motorcycle stores open on the weekend when the employees have worked all week and want to be with their families. 

Social Influences on Consumer Buying Decisions

When you are buying something important such as a car or a house, the opinions of others matter. People look for help through different reference groups. Reference group is a group in society that influences an individual's purchasing behavior. The primary membership group is usually the group of people where the opinions will matter while purchasing a house or selecting insurance for your car. This group consists of people who interact regularly in an informal, face-to-face manner, such as family, friends, and co-workers.

Do you think reference groups reduce the search and evaluation of decisions?
