This document summarizes an app called LetItGo that connects college students who want to sell furniture, appliances, and other items when they move out of student housing with students who want to buy reliable used goods at low prices. The app aims to make it easy for students to sell their unwanted items and for other students to find quality used goods from their peers. It will take a small commission from successful transactions and use promotional activities like WhatsApp and flyers to increase awareness on college campuses.
