Amazon doesn't sell the book at all?  I think I just realized something.

They did sell the book, but my mistake was not buying it from Amazon themselves, I got it from a book store. As Mothered said, they likely scanned the book and noticed it wasn't a part of their inventory so that's why they gave no refund for me

Interesting.  I didn't think that'd be an issue.  I've personally sent items I bought elsewhere and sent to them, just made sure it was part of their inventory.  My mate sent them something they've never sold lol, which is why I asked.  The more you know though, that's a good lesson

In your case probably the value of the items was smaller than 700
