Very Normal. I'm at 13 months, and never a penny. Don't give up though, you never know what could happen. The way to make money with amazon, or really, on Hubpages is to write product specific articles, and then feature that article on an amazon capsule.
You see, if you write about your boots, specifically the brand, etc; then people who are shopping on the net for those boots will find your hub, and perhaps, they'll buy them from your amazon capsule if you've interested them with your product review. If you do NOT interest them with your product review, then just maybe they'll bounce off of your hub from a Google ad that, contextually, should also be about some sort of boot or shoe that you are writing about, and that could at least make you something from adsense.
Of course the "boot/shoe" analogy is just an analogy, but the same would be true about any product article. Product articles will always make you more money than any other type of article here on hubpages, or anywhere else. Problem solving articles are also good for the same reason, and should allow for you to incorporate an effective amazon.com capsule with them too.
