Well, I finally got my Amazon astore to look good and embed in my joomla site. It took a little while, but once you install the iframe plugin, it works great. I also had to edit out all of the CSS stuff so it would fit nicely. Indigenous Peoples Issues and Resources Support Store I think it looks pretty slick.
I've done well with the sites I built from the html pages like the example above and also with the AOM script found in my signature.
I was able to get the astore embedded as an iframe into Joomla with a bit of hacking. PM me if you need help with this thing. Check it out.
Glad people liked the site. For Joomla, you just need to edit out all of the CSS in the astore you don't like and then install the iframe plugin. It really is not that hard, but my only beef is that I had to install two iframes on the page. One for the search function and one for the main astore. So far, getting better conversion then on the old one that was a stand alone astore.
