Haya Noticed That College Students Needed to Dress Up for Presentations

Haya noticed that college students needed to dress up for presentations but never seemed to have any ties, or at least not very nice ones. She decided she was going to set up a tie store on her campus and offer sports themed ties as well as solid colored ties in her school colors. She can put an announcement on the school's monitors that would display in the dining halls and student union. Which of the following customer touch points will give Haya the most information after her first weekend of selling?

A) Communication she sends via smart phones.
B) She should build a web site before she begins to sell on campus.
C) She should send an Email to all students on campus.
D) She should put a flyer in every mail box on campus.
E) Actual physical interactions when customers visit her store
