I want to build a facebook app.
Users will exchange clothing items with each other and set up a virtual thrift store. When a users donates real things to our real thrift store the will receive a promo code to enter at their virtual thrift store and receive a virtual donation to their virtual thrift store. When users reach a certain inventory size, they will receive coupons to use at the real thrift store. The application must have room for advertisements as that will be how we make money.
