About their links:
I really dont like the "product links" that they offer. These are the little iFrame boxes - I assume you know what I am referring to. Often if you put that code on your site, it will show up as a generic orange Amazon box instead - unless you refresh the page a couple of times. If you've had this happen on your own site, or seen it on others, it's just tacky (in my opinion).
I like the "recommended product links" section better - this is where you can put in a keyword and have "blocks" created... much like the sizes and layouts of Adsense blocks. In fact, I replaced Adsense on most of my pages with "Amazon ad blocks" of a similar size just recently.
Also, I like to use text links and actual images - which takes a little "manual work" - but the result is much nicer when displaying specific products or putting images & links with specific reviews.
So instead of using the little iFrame code they offer, I would copy my affiliate link from that... and then go to the landing page and grab the URL to the actual product image. For example, on a Black Eyed Peas CD, I would click through and get the actual picture URL:
http://images.amazon.com/images/P/B0009 ... ZZZZZZ.jpg
And link to that with my affiliate link:
[url=http://www.amazon.com/exec/obidos/tg/detail/-/B00096S3RC]

(that's not actually my affiliate link - just a direct link - but you get the point, I am sure)
p.s. I have sold
