Many people I talk to don't realize all the great features in Amazon. One feature I almost never see used is Listmania, but if you are an Amazon affiliate, you should be using this feature regularly.
Listmania is simple enough; you simply group together a bunch of Amazon products and put them into a list. For any article, this feature is a real find. If you are writing a how-to article, make a list of supplies the reader will need to accomplish the task, and link to it (using the "link to this page" link on the Site Stripe). (You can get to these lists by editing your profile.) If you are writing about attracting toads to your garden, compare toad houses in your list. It really doesn't matter what you are writing about; just create a list, drop a link in the article with your affiliate tag, and you've gotten another reader to Amazon.
Your lists can be informative, amusing, satirical, or whatever suits your writing style and personality. With 2,000 characters of comment for each item on your list, and numerous items per list, this is your chance to really show your readers how committed you are to your subject.
Just to see some examples, take a look at these lists I created for various purposes:
Henna hair dyes
As you can see, as long as you can find Amazon products, you can put them into a list and generate more affiliate sales.
