As the new academic year begins, and the rush among students to buy fresh sets of textbooks increase, chances are that you might miss the bus to find the right titles, in time for your first lecture. Worse, you might end up buying new books, and give it away to the scrap dealer at the end of the year. To put an end to such a cycle, and to promote a healthy exchange of knowledge, many online second hand book portals are doing their bit. Such portals allow you to buy second hand books at cheaper rates (almost half of the MRP). Likewise, few portals give you the option to sell books, as well as earn a few bucks. These titles range from academic textbooks to fiction and non-fiction books.
