I sent a like new book for buy back to ValoreBooks.com. The book included a CD. When my payment came, it was substantially less then the price quoted with no explanation. When I contacted them, they stated that the book did not include the CD and that someone would contact me back. After a week and no contact, I called again and was told they were still "looking into it" and would contact me again. After this, I called a week later escalated the problem (this has now been over three weeks since they initially paid me with no return communication). They stated that they suddenly found the CD and would mail a check for the remainder of the amount owed to me.
The check never came so I contacted them several more times, three to be exact, and the check was reissued. It's now been over 2 months since they received the book and the second check still has not arrived. It's been two weeks since it was reissued. Interesting how two checks never arrive and no communication from them.
Since then, I have sold several more books through Chegg and received prompt payment in the mail. I find it interesting that their checks make it to my mailbox but ValoreBooks checks seem to be issued but never received.
