Question form the case: 1. The idea of building the student stuff exchange is work and Siena can obtain the financial interest if the website is used by students. The situation that Siena and Chelsea met has happened by lots of students, if the website has been set up and work as they expect than the transection fee can be earn, because students whether the one want exchange stuff or the one who selling second hand stuff can save their time in the website instead of posting ads on Kijiji or ebay.

If Siena and Chelsea can cooperate with the student union then both
