I agree with izaidi. I would rather have a link to amazon. I may value your opinion and so if you present the link to amazon as a recommendation instead of an ad, I will likely click through and check it out. But just because I'm on your site and value your opinion, doesn't mean I want you as a third party in my purchase and I already shop on amazon anyways.
