Amazon kick-backs on My Practice Web Site

I signed up for Amazon.com’s referral reward program. When someone clicks through an amazon link and actually buys something (and doesn’t return it), then you get a kick-back for having the link there. I’m switching optoblog.com over to this Amazon advertising because google adsense hasn’t paid me anything, and it’s just annoying.

I’m also doing a “store” on my practice website. I wonder if it will earn anything. After giving a sample of a contact lens solution or a dry eye drop, I’ve had patients ask me, “Where can I buy this?”

Now I can tell them, go to my practice website! Does anyone want to argue for or against the ethics of that?
