Schools register with our service and start their free 6 month trial. Once registered ( a 2 minute job), we create an online uniform shop for the school. Schools then tell their parent community about the new service and parents start to use it at no cost. 
The parents create listings for surplus uniform items, look for bargains, or post wanted adverts. They either leave their phone number and/or an email address in the advert so that people who see it can respond to them directly. This completely cuts out any "middle man" and all profits go directly to the seller. Because buyers and sellers are from the same school, they can simply arrange to pass over the sold items which saves the hassle and cost of postage - brilliant!
