Second-hand books are previously owned books that sellers list at a lower price than a new copy. Each Bookaao listing shows the title, price, photos and the seller's description.
Choose a listing, check the edition and photos, and ask the seller a question in chat if needed. Then add it to your cart and check out. Bookaao arranges pickup from the seller and delivery to you, and the seller is paid after delivery.
Look at the cover, back and inside-page photos, read the seller's notes, and match the edition or year to the one you need. If something is unclear, ask the seller in chat before you order.
Most listings are exam preparation books such as JEE, NEET and AILET, followed by school textbooks (CBSE, state boards and ICSE) and higher-education textbooks.
