Hello, How thoughtful your mom was about your education! I am also in college now and most of the time I prefer to rent books or use electronic options. But I too have accumulated a few textbooks that are no longer useful. I recently found a great site where can I sell my books for cash https://booksrun.com/books/sell. They offer prepaid shipping labels for all orders and you get cash just 4 days after they receive your books. I like that everything is quick and convenient.
