NEVER use this garbage website. I rented a book and there was MULTIPLE instances where the book would not show up in my purchases and it said to "try again later". How am I supposed to try again later when my midterm paper is coming up? Should I tell my professor, 'sorry couldn't write it the textbook rental told me to try again later?' THIS HAPPENED DURING AN EXAM TOO!! THIS SITE SUCKS DO NOT WASTE YOUR MONEY HERE.
