Book exchange club

Hey fellow readers, I have a lot of physical books and was looking for ways to sell/exchange those but only found shops where i can do that, but i currently live in electronic city and it's a hassle to go to bloosom or somewhere else and was looking for an app or online group where we can do p2p book exchange or buy/sell instead of going to a shop. Didn't really find anything so created a telegram group, please join if interested.
