What's the best and cheapest (read: free) way to add an amazon affiliate store to a WordPress blog? Most of the free plugins I've found either don't do a good job, look ackward in my these, or just too much work to get going. WP Zon Builder looks good... but costly. Plus, I'd really like something that looks at the page content and then either puts related products within the content or in the sidebar.... and it'd be nice to find something that also converts keywords into links to the products. I found one, but they take 2 out of 8 links.
