Sweden's friendliest and environmental friendliest bookshop with the lowest priced textbooks.

This is our ambition, and we do what it takes to get there. We are here to help students to save and earn money on their textbooks while we at the same time save the environment. We were started in 2005 by two students and have since strived to constantly make it easier to buy and sell used textbooks for as many as possible.
