Where can I sell books in Chennai (or online) for a good price?

Hey folks, I’m looking for places in Chennai (or online) where I can sell second-hand books at a decent rate. If anyone has experience selling books or knows good spots, I’d really appreciate the suggestions! Also, if anyone here is interested, I’m selling **9 non-fiction books and 1 fiction book** at **40% of their online price**. They’re in great condition, and prices are negotiable. No need to buy in bulk—you can pick individual books. If you’re interested, DM me, and I’ll share the book list! Thanks in advance for any recommendations! 😊
