BEWARE! DO NOT EVER TRUST THIS WEBSITE!
I fell for their sellback price offer and agreed to sell my book to them. They sent me the shipping label.
Within 1 month, I have not heard back from Abebooks so I wrote them an email since they do not provide any phone numbers.
But they never responds any of my emails.
I think they just did scam me, took my book and refused to pay me with the price they offered.
It has been 6 months and it got to a point where I am getting tired to reach them and just let them steal my book.
I just want to share this so anybody else will learn from the mistake I made.
