Hey Aggies. Bookbag takes textbook exchange to the next level. No more browsing commerce websites for overpriced textbooks or resorting to your bookstore to sell your old books for a fraction of what you paid. With Bookbag, we create a community of students from UC Davis, all within the convenience of your phone. The benefit of being campus-specific is the constant stream of incoming and outgoing students taking many of the same classes. Calculus II students, for example, might list their textbooks the week of finals to receive a response that same day by others seeking that textbook. Buyers. Prepare for upcoming quarters by seeking books you know you'll need. If it's not available, add a book to your wishlist and get notified as soon as it becomes available -Check sellers' ratings if they have a history of reliability. Check that the edition is the one you need and even negotiate with the seller to save even more. Sellers. Get rid of those books without having to resort to super-low bookstore buyback prices or just tossing them in the closet -Post a listing of your book with all the relevant information. Let others know how much you want for it.
