"Sending them an invoice would just be an experiment, and ending up being an experiment in futility I'm sure. But if my review is still up on newandusedbooks.com without credit in 3 business days, I will send them an invoice. This is a legal hole, I think. Amazon says they own the content and can sell it (I'm assuming), so newandusedbooks.com will refer me to that policy. Still, it doesn't seem that newandusedbooks have set up protection from this. I'm not a barister or a lawyer, so I don't know. It would be interesting to find out. The point of contention is that they removed the links. Amazon lets you have a link in exchange for the review, but they let their affiliates remove those links. That seems unfair. I may call up my intellectual property lawyer friend about this." - Christine Cavalier
