At my achool store we sell alot of snacks like chips, and cookies and such for like $.50 and it sells like crazy ! Students like that kind of snacks to eat during the day. :) You should also sell like pencils and folders and notebooks becuase that kind of stuff everyone needs at school and they sell becuase when people run out they rather go to the school store because of convience. Hope that helps !
not knowing what type of school ie High School, Middle School or elementary school it would be hard to give you specific ideas but to start,t-shirts,sweats, shorts with school logo, pencils,erasers paper notebooks again maybe with school logo or mascot, sometimes as far as money you can get businesses to sponsor the school and donate items or at a much lower cost if your school has the budget to purchase things like these. Then there are things like teddy bears (stuffed animals) with your school name etc.
