I had three books that did not have isbn printed in them. I googled isbn along with the title, author and publishing date, and got the isbn. I then typed these in to your system, and the match came out. When I sent them to you, you initially described them as "awaiting scan". Fair enough, these might well take longer to process than books with the isbn printed inside. However, they were then all rejected, because they did not have isbns printed in them. Why? You could google them, same as I did. The books were as I described them. Instead, you sat on them for a week, with no intention of paying for them.
