The problem we have had with Chegg is that they retain your CC number AND they are not fastidious about logging in returns. My DD22 was charged $150 to replace a book…which she had returned. She didn’t think she had to keep a receipt of it getting mailed (first time for everything) so there was no way to prove that she had (although they managed to log in all the other books she returned at the same time.)
We would never use Chegg again. It is much simpler to buy from Amazon or the used College book store and sell them back on Amazon.
I think Barnes and Noble is doing a text book rent too…but we’ve never used them.
