College students need a quick, safe, convenient way to sell their excess items, or find great bargains on used college supplies, all the while interacting exclusively with their campus community.
Competitors
(and why they're annoying for students to use)
Craigslist: Misleading posts and ads; safety concerns (who's selling it?); location issues (how close to campus?)
Ebay: Auctioning process, Same security/convenience issues as Craiglist.
Facebook Free & For Sale: Long list of posts; cannot search for information; advertisements/ subleasing propaganda;
