Really good, thank you. Business model: monthly subscription to have access to database. 1. No shipping. Cities are often small, and highly dense. People´s cost of mobilizing (walking) to a meeting point is lower than the shipping cost. 2. I´ll never buy the books, they are owned by the users. They can exchange them, get them back later, or whatever their deal (Yeah, we know they will probably sell them for $ (I mean Q) but that´s not on us) 3. By having thousands of users pay $1 a month to get access to the info of the books of their neighbors, classmates, coworkers, etc who are actually just a few blocks from each other.
