Some people are saying Chegg is good, but the online complaints on the various complaints board tell a different story. A good alternative to Chegg for college students is Book Renter bookrenter.com. Here is one example of a bad review of Chegg.
I attempted to sell my textbooks back to Chegg. I received a notice that they had received my books on 10/22 and then heard nothing else for weeks. Today, I sent an inquiry as to when my payment would be sent out and was notified that the books were not in an acceptable condition. They did NOT reach out to me to notify me of this finding. I guess they simply just hoped I would forget. They have offered to “try and find them within the warehouse or donate them”. I have asked for a return of my books but I don’t see that going very far… VERY displeased. VERY dishonest company. DO NOT TRUST!
