I wanted to save some money renting from them instead of Chegg.com. Not worth it.
To begin, they didn't send me any type of email confirming that my book was shipped or a tracking number.
Then, not knowing where my book was, I called them on Feb 1st to know where my book was, they told me it was supposed to arrive on Feb 4th.
On Feb 5th I called them again to know where the heck my book was, and then they told me book was delivered, on the post office, Feb 1st.
Amateurs, never going to do business with them again.
