Hi! How nice that you want to buy your very own KallioPPE membership. Not only do you to get a 15% discount at the VU Bookstore and discounts in many of KallioPPE events and products, but you also support us in organizing many great events this year for our members, which strengthens the community and ensures that you are never studying alone! All the money from the memberships goes right back to you in form of events, cheaper merch, borrels, food, drinks, etc.
